Draw One in the Dark - Sarah A. Hoyt

This is romance-ish. The heroine likes a guy, then doesn't, then likes him. At the end she says they've been kissing off and on but even though they are living together, they're not jumping into sex.

The story itself took me a while to enjoy. At about halfway I didn't want to put it down but until then, I kept reading something else. For that reason, it's a 3-1/2 star book for me.
