Poems worth analyzing

Each chapter is a close reading of a poem, insightful and jargon free. Maybe a bit more context and biography for my taste, but still helpful. Reawakens the reading of poetry.

Beautiful and Hopeful...
Format: Kindle
“Olivia was right. The point of the choose your own adventure books was just that: Choice. It wasn’t about where you ended up; it was about the decisions you made to get there. And I don’t want to skip to the end anymore…” – Rosaline, When You Were Mine
If I could give this book 500 hearts I would, but my rating system only goes up to 5.
I’ve read a lot of great books lately, but When You Were Mine by Rebecca Serle surpasses 95 percent of them. This book was amazing from start to finish. I am a lover of all things Shakespeare, so when I saw the synopsis for this book it was an automatic must read, plus guys the cover is so pretty!
I absolutely loved the format of this book and the writing was exceptional, but I think what I loved the most were the characters. Serle did an amazing job of shaping the characters in this book, from Rosaline, Charlie and Olivia to Ben Rob, Juliet and of course Len, who by the way I loved from the second he was introduced.
The plot and pacing of the book were perfect. I didn’t feel rushed when reading about Rosaline and Rob or Rosaline and Len. Seeing things unfold throughout the story and finding out what happened to cause the two sets of Caplet’s to drift apart was a bit twist. I wasn’t exactly that at all and the fact that Serle was able to surprise me at countless turns throughout the book sort of makes me want to glomp her with hugs, because that’s hard to do to me.
There were so many amazing parts in this book that it’s difficult to choose favorites, but at the same time I had such strong emotions to certain parts of this story that I feel I need to mention them. First the Fall Back Dance. My god…I can’t even tell you how a part of my heart genuinely broke for Rosaline. I felt her pain, like literally. I got all teary eyed and my chest tightened up and I think I was like ‘OMG Rebecca you’re so mean!’ Haha. But the scene was so well written, that I experienced what happened there with her.
Another scene that touched me was the piano scene with Len. It will probably go down in my like top ten scenes in a book between two characters ever. The way Serle describes what’s happening and the emotion flowing through both characters and Rosaline’s reaction to the music, just, I can’t even. I wouldn’t use gifs to explain my emotions right now, but I’m not sure any of them would accurately capture what this books has done to me.
The third scene that really broke me and my raw hatred of Juliet was the kitchen scene between her and Rosaline. All through the first couple of acts of the story I was hardcore hating on Juliet. Like reach into the book and pop her on the head kind of hate. But after this scene…I just couldn’t do it anymore. Serle managed to take the essential villain of the story and feel empathy for her.
God, this entire book was just made of so much win. I want to draw pink fluffy hearts around it and love it forever. I am so glad I bought the hardcopy version instead of the Kindle version because I will definitely be reading this again…and then most likely again. I’m currently writing this while I shove the book at my sister and tell her to read it so she can love it as much as I do.
If you haven’t read When You Were Mine, for the love of god get on it. This has been on my reading least for so long and I’m just getting around to it now, but honestly I wish I would have pushed it up on my list. Amazing, no other words for it, definitely check it out if you get the chance and if it’s sitting on your list, well, move it up it’s worth it!

Refreshing Take On a Classic!
Format: Kindle
I have always been a sucker for "fractured fairy tales" and classic stories being retold by new voices (I think that's why I love Disney movies so much!). I have also always been a sucker for Shakespeare, in awe of the way he uses the dynamics of relationships to create stories that are as mind-blowing today as they were centuries ago when they were written. So when I heard about Rebecca Serle's When You Were Mine, it was essentially book candy on which I wanted to overdose!
Set in modern day southern California, When You Were Mine is the retelling of William Shakespeare's Romeo & Juliet from the perspective of Rosaline (are you as absolutely giddy over the premise as I was?! It's probably sad that I'm not being sarcastic at all right now!). If you don't remember Rosaline from middle school English class, she's the girl Romeo was madly in love with at the beginning of the play; until he met Juliet, of course. The first thing I thought of when I heard about this book was, "Why hasn't anyone else done this already?? Why didn't I think of this?!" (Honestly, maybe it has been done, but not to my knowledge).
So the idea is great, but what about the execution? I had high hopes when I started reading and overall I feel like the story delivered, but I admit I had to keep reminding myself that this is a contemporary Young Adult novel. Rob Montag and Rose Caplet are high school students who have been next door neighbors most of their lives. They have grown up as best friends but their friendship is beginning to blossom into more, much to Rose's excitement. But when her cousin Juliet moves back to town (after years of being estranged from Rose's family for a political scandal, no less), Rob becomes more interested in Juliet, leaving Rose (friendship and all) in the dust.
The story line and narration was very "high school" and I found myself becoming exhausted at times, like I was truly listening to a teenage girl babble. In one sense, this made me consider Serle as an incredible writer because she was authentically able to capture the voice of teenage Rose and maintain that voice throughout the novel. However, it did make reading taxing at times; almost everything Rose said consisted of her reflecting on something that had happened to her and her friends previously (think, "One time. At band camp...."). This did not slow my reading down necessarily (I inhaled the novel in 1 day), but all of the side stories definitely affected the pace of the novel. I think it also made me feel self-conscious, like, is this what I sounded like at this age? (Don't answer that, Mom!).
Aside from this Young Adult novel sounding like a super young adult (trying to emphasize that I can't really fault the novel for my biggest complaint), I really enjoyed the characters, the plot and especially the parallels between Shakespeare's version. The main characters were likable, especially Rose and her best friends. The only characters I wish the story would have given more dimension to are Rob and Juliet. I thought Rob was well developed until he fell for Juliet; I couldn't understand why such a great guy would go for this snotty girl, which made me feel like maybe I didn't understand Rob at all. (Of course, I'm sure Rose felt the same way and she is the narrator, after all). I was disappointed that there was not more depth to Juliet as well, but I suppose it's only fair that her side was mostly omitted from this story, as Rosaline's was cut out of the original, right?
What makes this novel stand out to me is how many emotions are vicariously experienced while reading: hopeful, happy, disappointed, angry, jealous, frustrated, sad, guilty, lonely, desperate, grieved, peaceful, and right back around to hopeful (there are probably a dozen more I left out). It's an extreme love story (we all know how it ends), but told by the perspective of Rose is refreshing and introduces the point of view of those who lived after Romeo and Juliet died. What is most rewarding toward the end is how Serle paints the picture of Rose's grief on top of a shattered heart. Without giving too much away, I feel like the conclusion was heartwarming and hopeful, despite its tragedy. Serle gives us something familiar that we can mourn differently than the first time we heard this tale.
Bottom Line: If you're a sucker for Romeo & Juliet, this is a must-read. If you're a sucker for YA I highly recommend this, too! If your reading preferences are a little more stuffy, then you might not be impressed (but that's your loss!).
