Ahh. Well. Welcome to the club How big a thing is the fantastic beasties? Because I can think of plenty of pulpy adventure stuff without too many of them, but with them becomes a bit more difficult. We're very much talking old sword & sorcery here - Robert Howard's Conan, that sort of thing. I'll echo Alucard on Theft of Swords and the Dresden Files. Also... going by reputation here, look up The Witcher books by Sapowski.
