Thank you to the publisher for providing this book for review purposes via Netgalley. All opinions are my own.Morena has lived long enough to forget why, every few decades she takes a potion that makes her forget everything. Why? She does not remember and prehaps she does not want to remember. As a necromancer death is her only constant. Razakel, the King of Hell still yearns in the Underrealm, he has ruled over hell for a very long time but one obsession has always remained. The witch who refused to remember him.Before you read this book, I would recommend reading the trigger warnings as this book is dark, the characters aren’t morally grey, they are pitch black. I wanted to love this book, I started off really enjoying it and there were some parts I loved but this book was not for me. I don’t think there is anything wrong with this book, it just wasn’t to my taste as I love a dark romance but this was a bit too dark for me. I loved Morena as a character and as we get towards the end we learn why she takes the potion to forget, this was quite sad but I can understand why she does it. Razakel was an interesting character and I did enjoy his interactions with Morena but I don’t think he deserved her. If you like a dark romance with characters who are truly dark not just morally grey, then I think you will enjoy this book. It did have some interesting ideas.
