Thanks for all the recommendations so far. I would be really grateful for books I can obtain freely. For example, Patricia Briggs looks great, Fizzy, but lack of money - I spend so much on cat food - means I stick to creative commons, PD, and freebies from Sony etc. I think the price of ebooks needs to fall (no printing etc), but that's another topic.
