The Flat Share, by Beth O’Leary

Colourful book editor Tiffy’s on-again off-again relationship is almost definitely over and she is broke and imminently homeless. Reserved shift worker Leon is in desperate need of money to deal with a family issue. This odd couple agrees to share Leon’s one-bedroom London flat, Tiffy taking residence for nights and weekends, while Leon is at work or at his girlfriend’s place. Following his girlfriend’s rules it’s never the twain shall meet, so they communicate by post-it notes and gradually get to know each other. This modern take on an epistolary novel works pretty well as we and they learn more about Tiffy and Leon’s flaws and foibles. It ends pretty much as expected, but it’s a fun ride to get there; along the way exploring the effects of emotional abuse and the British justice system.
