Ian Banks: Espedair street and Crow road are personal favourites.
Clive Barker: Imajica, Weaveworld. Mild fantasy horror.
Ken Follet: Century triolgy, if you like an epic. Pillars of the earth also very good, worth a gamble.
Conn Iggulden : Pick an era, I liked the Khan series.
Robert Harris: Most are pretty good, Enigma and Fatherland stand out.
James Ellory: La Quartet sublime, and follow with American tabloid.
Joe Abercrombie: Fantasy but not to much out there.
Donna Tartt : Secret History
Not exactly Dan Brown schlock nor Proust but good page turners.
