When Thea goes on vacation to her grandparents' house on the Jersey shore, she is not expecting to find the house full to the brim with family members. Nor is she expecting the gift her mother gives her: a journal in which she is supposed to record 100 true things. But most of all, she is not expecting how difficult it will be to control her compulsive lying and an annoying younger cousin whose persistence may translate to revelation.
A bit gimmicky and the conclusion is not as terribly shocking as it is built up to be. Thea is engaging enough and the targetted demographic (middle readers) will like her, but mostly this story is simply satisfactory. Not bad, but not terribly memorable or outstanding.
