Cupid

Love is both poison and cure, both knife and remedy. Rosa's best friend Catherine is dead, and she's certain Marquis Guilleme, Catherine's betrothed, is to blame. Her mother agrees—he must pay with his life. But Rosa knows Guilleme is no ordinary man: he's tainted, a monster, unkillable by normal means. To exact the perfect revenge, she must unravel his darkest secrets and destroy him. Yet will her own hidden desires consume her or set her free? No matter—Mother will guide her.
