How well do you really know your friends?

Joni, Deb, Eden and Trina try to catch up once a year for a girls' getaway. Careers, husbands and babies have pulled these old high-school friends in different directions, and the closeness they once enjoyed is increasingly elusive. This year, in a bid to revive their intimacy they each share a secret in an anonymous letter. But the revelations are unnerving. Then a fifth letter is discovered, venting long-held grudges and murderous thoughts. But who was the author? And which of the friends should be worried?

The Fifth Letter is a searing examination of the bonds of women's friendship groups, the loyalty and honesty they demand, and the pain of ending relationships that once seemed essential but might be outgrown.

'A delightful, heartwarming exploration of the twists and turns of true friendship, The Fifth Letter was simply delicious from the very first page to the last. This is the kind of book I can't get enough of relatable characters, a fast-moving plot and just the right amount of mystery. I was hooked!' - Rachael Johns, author of The Art of Keeping Secrets
