The Last Anniversary by Liane Moriarty

This is my fourth Liane Moriarty book and I've just bought another two. It wasn't my favourite but it's still a good story.

Sisters Connie and Rose live on a small island in Sydney Harbour. As teens they discovered an abandoned baby. The story takes place 70 years later when they are old ladies. They raised the baby, who is now 70 herself and has children and grandchildren. The mystery surrounding the abandoned baby has turned the island into a tourist destination.

I love to read books about people like me, living in Sydney with school age children. This is perhaps why I didn't enjoy this story quite as much as the others I've read by Moriarty. What Alice Forgot, The Husband's Secret and Big, Little Lies all had characters I could relate to more easily. That said, one of the characters suffers from post natal depression (thankfully not something I've experienced) and I though Moriarty's depiction of her was realistic and insightful.
