Jasper Fforde / Jodi Taylor / Ben Aronovitch
Loved (most not all) the Thursday Next books, Shades of Grey, some of the Rivers of London series and aspects of the Chronicles of St Mary's.
I wouldn't consider myself keen on fantasy but have really enjoyed these writers, the humour which feels quite particularly British, and how easy they are to read without being too lightweight.
Just for background, I also enjoy reading classics, some historical fiction, women's fic, modern fiction and what might be considered light / chick lit (so actually enjoy most genres!).
I would love some recommendations along the lines of the above (for info, have read Jon Rosenberg, who saw recommended on another thread, but I wasn't keen).
