If you want some horror Richard Laymon is the best. He's been described as Stephen King without a conscience so be warned that his writing is quite graphic. I think I've read all his books and loved them but they are hard to get second hand, not sure if you can get them a libraries. The Beast House trilogy were my faves of his and I've read them more than once.

If you are looking for some romance (but not the Mills and Boon kind) go for Jill Mansell. She's an English writer so her books are full of goings on in villages or in London. I've read a few of her books and love them. I keep trawling second hand book stalls to collect them. Head Over Heels is my favorite so far.

Ruth Rendell/Barbara Vine books are great if you like crime writing with really interesting characters - they are available pretty much everywhere & she's written heaps.
