A dark, twisty modern fairytale where three sisters discover they are not exactly all that they seem and evil things really do go bump in the night. Iris Hollow and her two older sisters are unquestionably strange. Ever since they disappeared on a suburban street in Scotland as children only to return a month a later with no memory of what happened to them, odd, eerie occurrences seem to follow in their wake. And they're changing. First, their dark hair turned white. Then, their blue eyes slowly turned black. They have insatiable appetites yet never gain weight. People find them disturbingly intoxicating, unbearably beautiful, and inexplicably dangerous. But now, ten years later, seventeen-year-old Iris Hollow is doing all she can to fit in and graduate high school on time--something her two famously glamourous globe-trotting older sisters, Grey and Vivi, never managed to do. But when Grey goes missing without a trace, leaving behind bizarre clues as to what might have happened, Iris and Vivi are left to trace her last few days. They aren't the only ones looking for her though. As they brush against the supernatural they realize that the story they've been told about their past is unraveling and the world that returned them seemingly unharmed ten years ago, might just be calling them home.

Zara Jones believes in magic because the alternative is too painful to consider--that her murdered sister is gone forever and there is nothing she can do about it. Rather than grieving and moving on, Zara decides she will do whatever it takes to claw her sister back from the grave--even trading in the occult. Jude Wolf may be the daughter of a billionaire, but she is also undeniably cursed. After a deal with a demon went horribly wrong, her soul has been slowly turning necrotic. It's a miserable existence marred by pain, sickness, and monstrous things that taunt her in the night. Now that she's glimpsed what's beyond the veil, Jude's desperate to find someone to undo the damage she's done to herself. Enter Emer Byrne, an orphaned witch with a dark past and a deadly power, a.k.a. the solution to both Zara's and Jude's problems. Though Emer lives a hardscrabble life, she gives away her most valuable asset--her invocations--to women in desperate situations who are willing to sacrifice a piece of their soul in exchange for a scrap of power. Zara and Jude are willing, but they first have to find Emer.
