Code Name Cassandra picks up right where When Lightning Strikes leaves off. Sixteen-year-old Jess has gotten the press off her back by telling the world her psychic ability to find missing people vanished as quickly as it had arrived, but the feds don't believe her: there's still a white van parked on her street, and she's sure they're bugging her calls. To escape this scrutiny (and also to avoid toiling away at her father's restaurant all summer), Jess takes a summer job as a counselor at a camp for musically gifted kids, but of course trouble follows her even into the wilds of Northern Indiana.

This book, and this series, is hardly groundbreaking, but I'm still entertained enough to keep reading the next book -- and Meg Cabot's poor grammar didn't bother me as much in this one (but maybe I'm just building up a tolerance for it).
