great book
Format: Kindle
I am really excited to meet the author at the book retreat this month. I really enjoyed this world that she built and most of the female main character Huntress is so awesome. She goes through a lot in this book and the ending; wow! I wouldn't have even guessed. I highly recommend everyone to read this book. I have been so lucky this year that almost all the books I have read have been, so far, 5 out 5 stars.

Fallen for the Fallen Angel – A Guilty Pleasure Worth Every Page
Format: Kindle
There’s something deeply irresistible about a dark academia or trial-based setting, a brooding and arrogant fallen angel, and a fierce heroine with enough sass to go toe-to-toe with him. Wings So Wicked is exactly that kind of book—and I devoured it in just a couple of days. To be fair, the plot isn’t groundbreaking. If you’re looking for something fresh and innovative in terms of storyline, this might not be it. But if your reader heart beats faster at the mere mention of enemies-to-lovers, jealousy-fueled banter, magical trials, betrayals, and forbidden tension—you’ll feel right at home. It’s like catnip for those of us with this particular weakness. The chemistry between the leads could have used a slightly slower burn to make the tension sizzle longer, but I still found myself completely invested in their dynamic. There are moments and phrases that feel a bit cheesy or underdeveloped, but honestly? I didn’t care. The vibes were exactly what I wanted. This book isn’t trying to reinvent the genre—it’s here to give readers like me what we crave: high-stakes magical drama, angsty romance, and the thrill of watching a badass girl and her brooding counterpart clash and spark. If that sounds like your kind of story, Wings So Wicked will hit the mark. Here’s hoping Book 2 turns up the heat and keeps the magic alive.

Fast paced romantasy you will not want to put down!
Format: Kindle
4.25 stars! I LOVED this book with similar vibes to Hush Hush, Fourth Wing, and The Serpent and the Wings of Night! It was fast paced with easy world building and will keep you turning the pages late into the night because you will not want to put it down! Huntyr is a fierce bad@ss FMC trained to kill vampyres her entire life. She is sent on a mission to go to the academy and earn her spot into The Golden City. Upon arrival, she is forced to room with the delicious fallen angel, Wolf, who is the only one who knows about her assassin identity. The romance, the plot twists, the secrets revealed, the battles, and the tantalizing training scenes had me hooked! And that ending…. I’m holding my breath in need to know hell! Read if you love: 🪽 Fae, Vampyres, Fallen Angels 🪽 Academy setting with magical trials 🪽 Forced proximity and slow burn 🪽 Rivals to lovers 🪽 Hidden identities and secrets 🪽 Tend your wounds “𝘖𝘧 𝘤𝘰𝘶𝘳𝘴𝘦 𝘐 𝘸𝘢𝘴 𝘸𝘢𝘵𝘤𝘩𝘪𝘯𝘨 𝘺𝘰𝘶.

Excellent Rivals to Lovers!!
Format: Kindle
The tension and banter between Huntyr and Wold was delectable. I absolutely love the fallen angel and all of his flaws. Huntyr is amazing too being a badass FMC with some major trauma. The world building was great and I enjoyed the training aspect of the story. The writing was immersive and was in the story the whole time. The ending had quite a twist that I hadn’t anticipated and made my jaw DROP. Excellent job! I also loved the narration. Laura is one of my fave narrators!
