Sorry, I realise my comment was ambiguous. I literally meant the titles of the books. If you can write for the YA market as well as the author of another set of SF juveniles, I'm very optimistic I'll enjoy them.

Somehow I find the GCA universe books a bit like candy, very pleasurable to read, but somehow not as satisfying as those set in the Portalverse. A little too much wish fulfillment I suspect.
