Stalking Shadows — Cyla Panin

A gothic YA fantasy debut about a young woman striving to break her sister's curse and stop the killing in her small French town -- now in paperback
Seventeen-year-old Marie mixes perfumes to sell on market day in her small 18th-century French town. She wants to make enough to save a dowry for her sister, Ama, in hopes of Ama marrying well and Marie living at the level of freedom afforded only to spinster aunts. But her perfumes are more than sweet scents in cheap, cut-glass bottles: A certain few are laced with death. Marie laces the perfume delicately -- not with poison, but with a hint of honeysuckle she's trained her sister to respond to. Marie marks her victim, and Ama attacks. But she doesn't attack as a girl. She kills as a beast.

Marking Ama's victims controls the damage to keep suspicion at bay. But when a young boy turns up dead one morning, Marie is forced to acknowledge she might be losing control of Ama. And if she can't control her, she'll have to cure her. Marie knows the only place she'll find the cure is in the mansion where Ama was cursed in the first place, home of Lord Sebastian LaClaire. But once she gets into the mansion, she discovers dark secrets hidden away -- secrets about the curse, about Lord Sebastian . . . and about herself.
