In no particular order for crime: Alex Gray, Peter Robinson, Ann Cleeves, Ben Aaronovitch (with added magic), SR Garrae (some romance), Helen Cox, Janet Evanovitch (slapsticky), JD Robb (some romance, a little futuristic), Kelley Armstrong's Rockton series (half thriller), Kerry Greenwood (1920's Australia), LJ Ross (Northumberland), Richard Castle (spin off from TV series Castle, first three are good easy reading), Robert Galbraith, Ruth Dudley Edwards (satirising all aspects of the Establishment, and definitely funny), Simon McCleave, and then the more old-fashioned Dorothy Sayers, Ngaio Marsh, Patricia Wentworth, Agatha Christie, Edmund Crispin, Minette Walters.
Thriller: David Baldacci, Lee Child (Jack Reacher).
