CJ St. John and Hannah Butcher meet while spending a summer as smoke jumpers in Montana. For CJ, it ends with some serious injuries, and Hannah saving his life. For Hannah, it ends with the conviction that she'll never overcome her temptation to freeze in moments of crisis--that she shouldn't even complete her training as a nurse because she'll be useless.
They've both got a lot to work through. Each can see the other's strengths, but only their own weaknesses. Despite bonding as teammates in an online adventure game, they both avoid meeting for months, until finally brought together again.
They're both kind, decent, likable people, and despite their own self-defeating impulses, they fortunately have other kind, decent, likable people around to push them in the right directions.
It's a novella, so not very long, and a pleasant way to spend a few hours.
