Petty Cash

It was a freebie and I was ready to give it up halfway through if it wasn't good, but somehow it got me. Even despite its obvious flaws - Rebecca and Foster have very little in common, forgive each other too quickly, there's a lot of unexplained drama (why his mom hates her, why she's so traumatized about the ex), the list goes on... - it is fun and made me laugh, so I kept reading and voilà, finished it :)
