The Last Anniversary (2005) is a novel by Australian writer Liane Moriarty.

Set on the fictitious Scribbly Gum Island, close to Sydney, journalist Sophie inherits a property from the now-deceased Connie, one of 2 sisters who raised a child ostensibly not their own but abandoned by a couple decades ago.

Connie & Rose – and their families – have been making a living out of telling the story of “Baby Munro”, abandoned by her parents who mysteriously disappeared; Scribbly Gum Island is now a tourist attraction.

The truth revealed is that *spoiler alert* the baby, named Enigma, is the child of one of the sisters.

The Last Anniversary has now been adapted as a television series. It is the 1st of Moriarty’s novel adaptations to be set and filmed in Australia.
