From the back cover
"Four years have passed since the slaughter that took place at the old Whitcome house. Four years since the tiny picture-perfect town of Antrim. Vermont was devastated by the ugliest event in the town's history. Now the bloodstained Whitcome walls have been painted over, the broken-down doors repaired. And a new family has moved in.
"Fifteen-year-old Will Crockett could have told his mother and stepfather that the bargain price on the Vermont house was too good to be true. But they never listened to him, anyway. Now weird things were beginning to happen: open doors that he knew he had locked; strange scampering sounds on the porch roof. A sense of being watched. His parents didn't believe him, but Will knew something was wrong -- something so twisted and evil that only a kid's imagination could conceive of its horror."
Guardian is an okay follow-up to Shadow Child. While the characters are well-written, the storyline feels disjointed at times. Citro could have easily streamlined the novel's flow into a more smoothly-told tale by eliminating some of the set-up scenes which read a bit clunky. Not only that, it seems as if the Gentry have more powers than they did in the first book -- at one point, they are almost god-like with their magic.
The novel's saving graces are Citro's superb characterization, his deepening of the Gentry's mythological roots (as well as their collective role in the world) and the last hundred or so pages which explode with supernatural carnage, violence and other sexualized horror.
If you are interested in reading this, I would recommend checking it out from a library before buying it -- unless it is for a bargain-basement price or you are a fan of Citro's writing who must own everything he has published.
