What if you learn something as an adult that makes you question your entire childhood?

This is the scenario the Rockwell sisters are faced with.

Esme: eldest child, control-freak, perfect wife and mother. In fact, her husband has run off with his dentist and their teenage daughter is live-tweeting the entire mess to her 3,000 followers.

Liv: middle child, fianc stealer, squatter. Holed up in her ex-husband's apartment with her acupuncturist and a bottle of whiskey.

Ru: youngest child, writer, runaway. Hopes to find inspiration for her second novel by studying the behaviour of elephants - and fleeing her fianc.

One-by-one the siblings return to the family home, where an even bigger drama unfolds. A box of old letters is delivered to the house containing the answer to the mystery they have all lived with, until now: who was their father, and why the hell did he disappear?

In the spirit of Wes Anderson's The Royal Tenenbaums film, this novel is a colourful, spirited and darkly humorous celebration of the impossibility of families.
