From back -
In this sequel to Summon the Keeper, Huff returns to a zany world where Keepers dash around Canada closing holes left by rifts in society - places where evil can leak through into the world. Claire, a Keeper, is faced with a most unusual situation. While trying to develop a relationship with Dean, a Bystander, or ordinary human, whom she met in the previous book, Claire accidentally allows the entry into the world by two unusual entities: an angel, who takes the form of a teenage boy, and a demon, who becomes - what else? - a teenage girl. Angels and demons normally are not equipped with genitalia and hormones, and their respective attempts to deal with these attributes cause confusion for Claire and her seventeen-year-old sister, Diana, who is also a Keeper. All confusing perhaps, but Claire; her sidekick, the talking cat Austin; Dean; and Diana, along with assorted other characters, manage to set the world to rights eventually, sprinkling wisecracks far and wide along the way.
A fast, fun read - slightly longer than the first and just as strange and humourous.

Caboodle seems to have stolen these (ahem) last time she was down, so I'm assuming they're on her To Be Read shelf now.
