I've just finished reading UK writer Paul Sullivan's new novel A
Fictional History of Britain Part One. It claims to chart the earliest
ancestors of Arthur, based broadly on the Geoffrey of Monmouth
material. But it's an absolute hoot - a comedy in the Pratchett/Douglas
Adams vein, heartily recommended! Check it out (there are downloads and
previews) at www.lulu.com/sullomeo. It should be in the shops too, but
I haven't seen it there yet.
