In this thrilling paranormal YA romance debut steeped in folklore, two estries-owl-shifting female vampires from Jewish tradition-face New York's monstrous underworld to save the girl one of them loves with help from the boy one of them fears before they are, all of them, lost forever.

Clara loves rules. Rules are what have kept her and her sister, Molly, alive-or, rather, undead-for over a century. Work their historic movie theater by day. Shift into an owl under the cover of night. Feed on men in secret. And never fall in love.

Molly is in love. And she's tired of keeping her girlfriend, Anat, a secret. If Clara won't agree to bend their rules a little, then she will bend them herself.

Boaz is cursed. He can't walk two city blocks without being cornered by something undead. At least at work at the theater, he gets to flirt with Clara, wishing she would like him back.

When Anat vanishes and New York's monstrous underworld emerges from the shadows, Clara suspects Boaz, their annoyingly cute box office attendant, might be behind it all.

But if they are to find Anat, they will need to work together to face demons and the hungers they would sooner bury. Clara will have to break all her rules-of love, of life, and of death itself-before her rules break everyone she loves.

In this stand-alone debut, A. R. Vishny interweaves mystery, romance, and lore to create an unputdownable story about those who have kept to the shadows for far too long.
