Well…
Format: Kindle
I enjoyed the book, it had an interesting plot and magic system. The book is full of smirks, hissing, and crying. OMG the crying! The FMC cries from front to back of the book! I absolutely loved Daggermouth and read this book bc that, but I feel like she had a different editor maybe?! Idk what happened, but this book would have been so much better without the MMC smirking on every page that the FMC was crying on.

Top Book of 2024
Format: Kindle
May Contain Spoilers! Where do I even begin? I'm still in shock of how amazing this book was, how it touched my heart, and now how I have to wait for H. M. Wolfe to write the second. Because those last few chapters...went from 0 to 100 quick. So much new information, new relationships and loss, that now the tides have turned, and we NEED more. This is a fantasy book of love, loss, the power of friendship, and finding one owns strength. TBOC is about Hyacinth whose home is at Asrai’s Academy for Orphans. She was torn between the safety of home or leaving it all behind for a chance at a new life. But when a mysterious messenger appears, whispering rumors of a God among Fae, everything Hyacinth thought she knew about the Realms comes crashing down, and she must now make a new journey. This book ate me up and spit me back out. I was not anticipating the emotions I would feel within these pages. I'm talking I was laughing, then I was swooning, then I was on the edge of my seat, then I'm ready to slap someone, then I'm rooting so hard for certain characters I don't wan to stop, then my heart is broken, then I'm excited af.... it was all an emotional rollercoaster. The last few chapters contained a lot of new information, so of course as much as it doesn't leave off on a complete cliffhanger, I was over here like scraping the bottom of an ice cream cup, wanting more. The magic system starts out ambiguous, but as you continue reading you start to get more and more to build off of and start to piece together the world H. M. Wolfe created. TBOC brings in eight main characters that test alliances, grow in friendships, fall in love, become a team, and even break bonds. The friendship among the girls was everything. Ata is a spit fire, Pria is sweet yet terrifying. The banter and protectiveness these three had for one another made me want to join in with them for breakfast. I liked how there was multiple romances going on at once. Yes we have the main characters, but it just wasn't always about them, and it was great to see how others shifted and grew too. And last the romance, I've never rooted so hard for two characters. We're talking slow burn between them. In the beginning you're not sure how this is all going to play out, but Landers is a tatted, "touch her and die" kind of MMC, which who cannot love that? Hyacinth definitely had to grow within the chapters and learn how to be strong, because sometimes she was making me mad and I just wanted to step in there for her. But Landers was everything she needed and it was so well written, which is why by time you get to the end you only want more of them!

cliffhanger, no 2nd book in sight
Format: Kindle
The book itself was pretty good. The plot is unique and full of suspense and action, although some of it felt redundant. I particularly enjoyed the realistic growth cycle of the female lead from abuse survivor with low self-esteem to badass warrior. I never would have read it though if I had known this is not complete, and there is no information available on the next book.

4.5
Format: Kindle
4.5 The Book of Cin relies heavily on the progression and growth of our fmc, which I don't hate. It shows us the girl she was and what she allowed and who she then grows into by the end due to all the events that happens within the book. This journey - physically, mentally, and especially emotionally - takes us through her current and past experiences and expresses how one can grow from trauma. Her support group is invaluable, and the new relationships she forms prove to be just as prominent to her and her growth. This is truly a story that thrives on the characters growth throughout the book and sets us up in how to see her for the coming books. My half star comes from the pacing. Though I *thoroughly* enjoyed the ending and seeing this growth take full effect, I believe that it came with just too many pages. Sitting at about 500, we get intimate and detailed scenes that we could have maybe gone without. Oftentimes, I found myself daydreaming away from the book until something more prominent peaked my interest again. I understand the depth the book goes into to fully establish this character development and the setup that this provides for the rest of the series, but I truly do believe there were scenes that could have been cut out to help with the pacing. If you're not into slow pacing (and usually I'm not), this book is still worth the read. The ending more than makes up for it, and it is absolutely detrimental to the story that we get the events that occur and see the development take shape in front of our eyes. It makes you fist pump the sky by the end.

All the stars! Emotional! Incredible!

This was one of those books I have a hard time reviewing because I struggle to find the words to adequately express how incredible it was! This book deserves every single star! It is heart-wrenching, emotional, and heavy. The depictions of self-worth, guilt, loss, love, and everything in between were done beautifully. There are multiple romances to root for and the development of the plot/world was executed brilliantly. It has an amazing set of characters that will bring out not only all the rage/hate but also sacrifice that will impact your soul! The ending of chapter 19 will live rent free in my mind and is now one of my top favorite moments from any book and why Landers will forever take a top spot in my all-time favorite book boyfriends! The depiction of what true friendship should be is also well represented! Ardan stole my heart as the best side character and if you’ve read this we need to talk (iykyk)!! I absolutely need the next book to see what happens next!! “𝘐 𝘴𝘩𝘰𝘶𝘭𝘥𝘦𝘳𝘦𝘥 𝘺𝘰𝘶𝘳 𝘱𝘢𝘪𝘯, 𝘯𝘰𝘵 𝘢𝘴 𝘢 𝘵𝘦𝘴𝘵𝘢𝘮𝘦𝘯𝘵 𝘵𝘰 𝘺𝘰𝘶𝘳 𝘸𝘦𝘢𝘬𝘯𝘦𝘴𝘴, 𝘣𝘶𝘵 𝘣𝘦𝘤𝘢𝘶𝘴𝘦 𝘮𝘺 𝘰𝘸𝘯 𝘴𝘵𝘳𝘦𝘯𝘨𝘵𝘩 𝘤𝘳𝘶𝘮𝘣𝘭𝘦𝘥 𝘪𝘯 𝘵𝘩𝘦 𝘧𝘢𝘤𝘦 𝘰𝘧 𝘺𝘰𝘶𝘳 𝘴𝘶𝘧𝘧𝘦𝘳𝘪𝘯𝘨.
