Liked it
Format: Kindle
I liked the worlds and the characters. The prophesy is confusing in that I would think, since all worlds ore on a path to destruction, the angels would want their world to be saved. I am sure there is more evil that will be revealed as the series proceeds. I dislike a prolonged “poor little me” trope and the main character has moved past that, thankfully, and began to show a fierce attitude as the novel progressed. The last portion of the novel had some great action. It’s worth reading, just be patient with a slow start.

Could not put this book down!
Format: Paperback
Binge read quality!! Finished in 2 days I was in a dilemma with this book. I couldn't wait to finish because it was so good, and yet I didn't want it to end, because it was so good. Staying up til 2:30am is the highest complement I can give to a book. Current day with Gothic feel. The story pulls you in immediately, and there is never a part where it feels dull, or that you need to skip through. Mysterious with plot twists, especially the end. I love how there were flashbacks from the past intertwined with present day. Gave a great backstory that only came together at the very end. Spicy for sure, and fit in perfectly with story. Great character development so that you could empathize with both of the main characters.. Lucian and Isa. Check Trigger warnings first!
Highly recommend this book

Easy Read With a Wild Ending
Format: Audiobook
This was a really easy book to get pulled into. The writing flowed well and I flew through it without feeling bogged down at any point. While I don’t think it hit me as hard as some of Keri Lake’s other books, I was still invested the whole time and needed to know where everything was going.
The atmosphere and mystery kept me hooked, but the ending? That twist completely caught me off guard. I honestly did not see that coming at all. Even though this one wasn’t my favorite from the author, the final turn alone made it worth the read.

A masterfully written, stunning, gothic romance!
Format: Kindle
Lucian Blackthorne . . . my, my, my. Be still my romantic, sinful, dark heart. This male lead is one of the most addicting, flawed, sensual, erotic characters I've ever read. fanning myself I loved his dark, thrill-seeking, possessive, obsessive, carnal nature. Seriously, where can I find one?
I digress. Lucian is a scarred man with secrets but that's only the tip of the proverbial iceberg. He's layered as deeply as an onion and it's addicting to peel back each one. He's a rich, powerful alpha male but there's so much to the man the town refers to as the Devil of Bonesalt. He's marked by loss, lies, a painful past, and the shadows of his choices in life. The Blackthorne name bears tragedy, turmoil, and an affiliation with the macabre.
Isadora is a strong female lead. She's young but her life hasn't been easy. She's flawed, haunted by the past, and as much an outcast as her new employer, the enigmatic, elusive Lucian Blackthorne. Her new position brings her into the fold, learning the darkness, deceit, sadness, and crimes elicited against the Blackthorne family. It only takes one night, one passionate encounter with the master of salt and bones to change her life forever.
Scandal, intrigue, tortured hero, suspense, thrills, mind-blowing twists, jaw-dropping secrets, and enough sensual bedroom scenes to set your kindle on fire.
This is a MUST READ. One of the best reads of 2022 for me. LOVED it!!
