Meryl Yourish has been around the JBlogosphere from the very start, years longer than even me. Recently she wrote a fantasy novel for young adults.
If you or your kids are into that, check out Darkness Rising: Book One of The Catmage Chronicles.
Knowing Meryl and from reading the blurb, I bet that there are a few Jewish themes to be found in the book.
And you'll especially like it if you are a cat person :)
