Really good book that took me by surprise. It's not as light and frothy as the cover and the back blurb make it appear.
Two people who use each other to get their families off their back. At least, that's how it starts out.
They're both carrying some emotional baggage (one fears they may be responsible for their father's suicide and the other is a cancer survivor). Lots of nutty relatives around to keep things from getting too depressing.
