Do you like Dean Koontz? Anything by him is excellent (though sometimes twisted and usually featuring a dog) but I think my favorite is Strangers. Kind of out there with the plot but the relationships he builds are A++.

Or if you're in a sci-fi/fantasy kind of mood, you can try Ender's Game.

Oooh or anything by Chaim Potok, but especially My Name Is Asher Lev and it's sequels.

Ever read any Anne McCaffrey? I love the Pern series.

... I'll stop rambling now.
