I recently read The Girls of Central High Aiding the Red Cross, by Gertrude W. Morrison, the seventh book in the Girls of Central High series, which I know absolutely nothing about.
This is the only Girls of Central High book I’ve read, but it sort of doesn’t matter. These series are all pretty similar, and this is one of the ones where the first chapter includes a short recap of what has happened in each previous book. In this case, each previous book appears to have included a lot of sports. This one doesn’t, really, except for a bit of ice-skating.
