Faerie Tale(1988)

Raymond E. Feist

Phil Hastings was a lucky man—he had money, a growing reputation as a screenwriter, a happy, loving family with three kids, and he'd just moved into the house of his dreams in rural of magic-and about to be altered irrevocably by a magic more real than any he dared imagine.

For with the Magic came the Bad Thing, and the Faerie, and then the cool... and the resurrection of a primordial war with a forgotten people-a war that not only the Hastings but the whole human race could lose.
