MacIntyre, Rothfuss and Abercrombie as all recommended above
also add Wodehouse (Jeeves & Wooster, Blandings etc), and MC Beaton’s Hamish Macbeth books for some lighter reading
Robin Hobb for fantasy
John Connolly for crime with fantasy undertones
Jim butcher’s Dresden files for fantasy / crime crossover
Chris Simms for Manchester based crime drama (book 6 of the DI Spicer series currently free on kindle this weekend)
Stephen Booth for Peak District crime drama
After my suggesting those to my dad, he now recommends Robin Roughley. Not yet had the chance to read any.
Non-fic, try Tony Hawks (round ireland with a fridge, one hit wonder, piano in the pyrenees), and Tim Moore (The cyclist who went out in the cold, French revolutions, Gironimo, Do Not Pass Go – the latter is non-cycling, it’s about the monopoly board)
