Marinda has kissed dozens of men-- and they all die afterward. She is a visha kanya-- a poison maid. Marinda serves the Raja by dispatching his enemies with only her lips as a weapon. Until now the men have been strangers, enemies of the kingdom. Then she receives orders to kiss Deven, a boy she knows too well to be convinced he needs to die. She begins to question who she's really working for... and how much she can afford to lose.
