This gritty and mysterious love story will stay with me for a long time."—Cath Crowley, author of Graffiti MoonPraise for Rebecca Lim's Mercy series:"A modern-day Quantum Leap for the teen set (but with angels): well-rounded characters, including a particularly strong heroine; beautifully written prose; and a dark and twisting plot that kept me guessing until the very end.
