Wow - thanks for all those very quick responses! Have tried a few Patricia Cornwells but haven't got into them to the same extent as Reichs. Koontz didn't do much for me, but thanks for reminding me of Janet Evanovich - I read One for the Money as part of my Info Studies course last year and did enjoy it, so there's a new avenue!

Most of the other suggestions I haven't tried yet, so will head to the library tomorrow armed with a list!

For the next 4 months I'm a pregnant SAHM and so will have lots of time to read. Last year I was studying full time and am worried I'll get bored now that I've finished, and I can't get a job as baby is due in May! Time to find loads of new exciting authors, thanks!!
