Meet a man. Lure him in. Kill him with a kiss. Until one night Harlow kisses a mark and he doesn’t die.

Worse, the man immune to her kiss is her new betrothed, Henry Havenwood, and now he knows about her double life. The only way to protect her secret and her city is get close enough to Henry to figure out why the Havenwoods have reappeared after years of silence and what they have planned.
