Nine Perfect Strangers by Liane Moriarty (2018)

Every time Liane Moriarty comes up, I feel a little glow of having 'discovered' her with her first novel Three Wishes (2004!) Every single novel since then has been a treat.

Rich characterizations and complex relationships in unique situations are Moriarty's stock in trade. This novel is no different and has a particularly unique setting. Nine strangers meet at a health resort. Secrets unfold. Unexpected things happen. AND there's a kickass, menopausal, romance writer heroine called Frances. 

Endearing, absorbing, and so readable.
