My comments on The Vampire Tapestry are up at Fanlit on the Suzy McKee Charnas page. After you click on the link you’ll have to scroll down to find it.
The first half of the review is choppy because I hacked 500 words out of it before I posted it. This is an older book, but still holds up. Charnas has interesting observations about people and she took the challenge of inventing a nonhuman predator seriously.
