A review by saguaros
Claudia and the Phantom Phone Calls by Ann M. Martin

I mean, the best part about these books right now is the nostalgia and the 90s references. But I appreciated that efforts were made for Claudia's voice to be different than Kristy's in the first book. It was pretty yikes, though, what with the whole "he only teases you/makes you mad/stalks you/etc because he likes you" major plot point.
