Mary Catelli’s Erratically Updated and Exceedingly Unorganized Journal (she forget ‘Delightfully Named’) has a brief, but delightful review of Perseus Corbett and the Forbidden Valley, which can be found here.
It’s really too brief to make sense quoting from it, except to say that it opens with the encouraging trio of “Action! Adventure! Romance!” Just go read it, then check out the book itself. Oh, and take a gander around the rest of her site while you’re at it.
