In this high-octane conclusion to the Unseelie duology, which Andrew Joseph White calls "a portal to a world of glimmering fae and blistering magic," two sisters discover that the things that make them different can lend them more power than they ever imagined. Isolde Graygrove has always put her changeling twin sister first. But ever since Seelie returned from the faerie realms with a newfound confidence in her magic and secrets she's keeping even from her twin, Isolde can't help but wonder: who is she, if not her sister's protector? Seelie knows there are some problems even magic can't solve. Like the distance between her and Isolde, the terror of her growing and unfamiliar emotions for Raze, or the fact that the world's last firedrake has imprinted on her like a baby duckling. Still, she can't help but try. When Seelie accidentally splinters the three realms, tangling the human and faerie worlds together into something new, the vicious faerie Gossamer is determined to take full advantage of the chaos unleashed. Seelie and Isolde will need to spill their secrets, decide who they can trust, and navigate the sinister glamour of the faerie courts to save humankind and fae alike.

The start of a swoony, high-energy duology that Emily Lloyd-Jones, author of The Bone Houses, calls "reminiscent of classic fairytales yet brimming with a charm all its own." "A world of glimmering fae that sparkles with mystery, adventure, and enchantment." --Andrew Joseph White, New York Times bestselling author of Hell Followed with Us Iselia "Seelie" Graygrove looks just like her twin, Isolde...but as an autistic changeling left in the human world by the fae as an infant, she has always known she is different. Seelie's unpredictable magic makes it hard for her to fit in--and draws her and Isolde into the hunt for a fabled treasure. In a heist gone wrong, the sisters make some unexpected allies and find themselves unraveling a mystery that has its roots in the history of humans and fae alike. Both sisters soon discover that the secrets of the faeries may be more valuable than any pile of gold and jewels. But can Seelie harness her magic in time to protect her sister and herself? "Housman's stunning debut is the sort of love letter only an autistic author could write. Fae canon has been waiting for this one." --H.E. Edgmon, author of The Witch King
