About this book

“Logic bows at the throne of obsession.” When Wren discovers a body and Castien in the tunnels on the same night, she’s certain she’ll never be able to trust him again. But that doesn’t mean she no longer needs him. In order to discover the killer taking down their fellow students, Wren is forced to rely on Castien’s strategic mind and his knowledge of the Obsidian Order. Wren wants nothing more than a cordial alliance, but Castien is intent on winning much more than her loyalty. He longs for her heart. As they learn to trust each other again, the secret of Wren’s stolen journal looms over their fragile happiness like a storm cloud on the horizon. Will they be able to withstand the tempestuous winds, or will they be ripped apart in the end? Find out in Tides of Secrets, the epic conclusion of the Obsidian Academy Duet, a love story tinged with obsession and drenched in yearning.

Hauntingly romantic and soul wrenching!

"Tides of Secrets is the hauntingly romantic, soul wrenching sequel in the Obsidian Academy Duet. Wren continues to struggle while Castien is ever constant in being there for her. While she grows as an individual, her determination and strength shines through when she needs it most. Castien is the ultimate hero as he protects her, supports her, comforts her, and teaches her. As he tries to make up for mistakes he has made, he becomes a better man, especially with Wren at his side. His longing for her is tangible and his patience is admirable. In the end his only concern is her. It was fascinating how connected Wren and Castien became in heart, thought, and purpose. Tides of Secrets is the perfect ending to this duology and a must read if you love epic murder mysteries, overcoming betrayal, devoted friends, and a love story that will take your heart on a journey you won’t forget. Just amazing! Tropes: romantic fantasy = light vs. dark = found family = secret letters = dark academia = secret society = regency vibes = swoony kisses Favorite things: - The letters - The dagger - Castien chasing Wren to get a letter - She takes care of and reads to him - His complete devotion to her - Their first kiss - Finn’s loyalty & way he brings light to dark situations - The epilogue! Favorite quotes: "The loss of her words would be unbearable. He had come to rely on them. They were his air and water. Vital. Necessary for survival in this shadowy landscape." - Castien "I don't want every good thing in the world ... I only want you." - Wren Happy reading! ["

Best book I've read in a while!!!!!!

"This book is legitimately one of the best fantasy books I have read in a long time. I was invested in the story, and I was swooning as the characters' relationship developed. I am so in love with how Castien was written, and let me just say, he is a yearner. It's so beautifully written, and it was such a fitting sequel. The pacing was truly great, and you get so wrapped up in the world and their relationship that you almost forget anything was wrong in the first place. I highly recommend you read this duology, and any book that comes after this one, because A.R. Conwell is truly magic. She is such a refreshing author, and having no spice is amazing, but she gives us these beautiful, intimate moments between the characters that are so much better and more beautiful than they ever could have been if it were explicit. There were so many moments where my heart was hurting for Wren, and you can see that Castien's was as well. PLEASE read this book, I promise you, you won't regret it. ["
