Fire dreamed of water, but the first sip would be its last.
Gilde has spent her life isolated in the wild marshlands, a place too wet for the dragon to go. She's safe there, according to her father. So why is he asking her to leave with him now that she has come of age? There is more to Gilde's family than she knows, and debts need to be paid.
Betrayed and shattered, she wakes in a crumbling mountain castle with the beast of her nightmares. Except this dragon speaks like a man and reads books. His kindness confuses her and opens a forgotten longing in her heart, all while Gilde plans her escape from a mountain full of secrets.
This place can unveil her past and why she was sacrificed to the beast—truths that may put both their lives in danger if they can't learn to trust each other. But how can Gilde ever trust again? Especially after she discovers what dragons truly are.
