Trees in Books

Okay...so loving trees as I do, I really enjoy when they play some kind of pivotal (A Tree Grows in Brooklyn), or even minor role in a book. :) You know how some readers just love pets in a book? Well, I'm actually one of those too. But today we're talking about trees. ;-)

I just realized that the cover for Close Quarters is probably one of my favorites, not only because it has a hot rendition of my hero, but a tree. LOL Hmm... what other delish romance covers have trees on them?
