When thirteen-year-olds Marcus, a supernatural matchmaker, and Lena Perris, a soul collector, kiss at a party on a dare, they soon realize their powers have swapped. Now logical-minded Lena finds herself with the love touch, and ultra-emotional Marcus has death at his fingertips--and setting things right has become a matter of love and death.

Just when Marcus and Lena think life is back to normal, Lena's reaper powers jump into their new friend, Natalie, and Marcus's matchmaking abilities are transferred to his older sister, Ann-Marie.
