Emrin is on the cusp of becoming a full-fledged apothecary. She also provides care for the eerie fae folk, devious creatures who govern the elements, shape the seasons, and toil under a curse: all they touch turns to gold. When she is accused of murdering a faerie and spirited away to face a death sentence, she resolves to do anything to save herself-including entering a deadly deal with the wicked prince Helas. The pact is simple: become the court's alchemist and rid them of the curse. What began as a bet to win her freedom escalates into a mission much greater than herself, and her time is running out. Sinister ploys conspire to plunge the elven court into madness, and when their plans devastate the land, lush Elvenfall will be torn asunder. Now Emrin must prove her courage and carve an untrodden path to the core of Elvenfall's magic and join forces with Helas, as despicable and exasperating as he might be. But betrayal lurks everywhere, and she must risk her life to unravel the hidden conspiracy-and discover where her loyalties lie-before it's too late: because the land is dying, and magic alone can't save it.
