In a sensual paranormal romance, a teen girl's doppelganger from 1348 Florence lures her into the past in hopes of exacting a deadly trade.

It was meant to be a diversion - a summer in Florence with her best friend, Liam, and his travel writer mum, doing historical research between breaks for gelato. A chance to forget that back in Vermont, May's parents, and all semblance of safety, were breaking up. But when May wakes one night sensing someone in her room, to find her ghostly twin staring back at her, normalcy becomes a distant memory. And when later she follows the menacing Cristofana through a portale to 14th-century Florence, May never expects to find safety in the eyes of Marco, a soulful painter who awakens in her a burning desire and makes her feel truly seen. The wily Cristofana wants nothing less than for her and May to inhabit each other's lives, but with the Black Death ravaging Old Florence, can May's longing for Marco's touch be anything but madness? Lush with atmosphere both passionate and eerie, this evocative tale follows a girl on the brink of womanhood as she dares to transcend the familiar - and discover her sensual power.
