Jack and Jaide are rambunctious twelve-year-old twins whose father is rarely home. Then one day he returns in a bolt of lightning, and their house is destroyed. The twins go to stay with their mysterious grandmother, who talks to her cats and can make them forget things with hot cocoa. They're not sure they can trust Grandma X--but it seems that an equally mysterious, far more frightening magical force is after them, and she may be their only ally.
Definitely the worst book Nix has ever written. I mean, it's fine, but it's nothing special. Ever single character needs more personality. I was annoyed that everyone kept the magical secrets from the twins' mom--even her husband keeps her in the dark! There's no real explanation for why, which makes me think the mom is kept ignorant of her family's skills and adventures simply because it's such an expected component of YA fantasy. Frustrating! And their adversary is called "The Evil"? That's the best they could come up with? I blame Nix's co-author, Sean Williams, who writes Star Wars tie-in novels.
