f you want a good horror/sci fi I would recomend Dean Koontz, specially from the corner of his eye, watchers, the dark place, in fact anything exept the odd thomas books or the frankinstein ones.
A great book that I have read many times over is Tandia by Bryce Courtenay, its about a coloured girl in South Africa.
It depends what sort of genre your into, I dont do romance or murder/mystery so cant help you there!
