SOUL ENCHILADA, by David Macinnis Gill (Greenwillow, 2009)(12+). Bug's grandfather sold his soul to the devil for a '58 Cadillac. Now that he's dead, payment is due. But somehow, he escaped, which means that Bug is responsible - when she was thirteen, her grandfather tricked her into co-signing.
Even with the assistance of her longtime crush Pesto (who is not what he seems), can Bug make sense of her life and save her immortal soul and/or her Biarritz?
SOUL ENCHILADA is warm, funny, and full of grace. Richly detailed, Bug and Pesto are engaging and believable; readers will be enthusiastically rooting for them to smite the devil. Highly recommended.
