I read a military fiction romance a few years ago, and now I seem to have deleted it out of my (extensive) library. I'm pretty sure it's part of a series.
There's a rescue mission. The girl and one of her male teammates have to convince someone to authorise it because they swear the guy is still alive. They find the guy, and he's in really bad shape. They get him home and he disappears to a cabin after he gets out of the hospital. The girl tracks him down and stays with him (there's something involving a hidden car battery) and then she ends up back at her place in San Francisco, and I think eventually he meets her there.
I've spent about 2 hours looking for it tonight and can't find it. It's driving me crazy!
