Edira Brillwyn is a threadmender. She holds a rare, lifesaving power that can cure disease and heal injuries in the blink of an eye. But magic always comes with a cost, and saving anyone sacrifices a sliver of her own life. She's always kept her abilities hidden...until the powerful Fernglove family discovers her secret. The Ferngloves are charming and beautiful, possess powerful magic, and don't take no for an answer--especially Orin, the head of these ruling elites. When Edira's brothers unexpectedly contract blight--an incurable virus killing people throughout the town, and an illness too strong for her to heal them both--Orin offers to help. Together at his estate they'll research a cure while Orin slows their sickness and Edira hones her magic. His kindness and honesty surprises Edira, as does her undeniable attraction to him. But the other Ferngloves are suspicious of her power and may be more dangerous than the ever-present disease. The longer Edira stays within the confines of the Manor, the more the family's pristine exterior begins to crack--until Edira discovers a terrifying secret and must choose who she can save and at what cost...
