An Amazon Graphs and Washington Post bestseller.

It was supposed to be an ideal reunion: six university or college friends together again after twenty years. Host Ali finally has the lifestyle she always needed, a career she could be proud of and an excellent family with her college boyfriend, now hubby. But that night time her closest friend makes an accusation therefore in what You Did surprising that nothing will ever be the same again.

When Karen staggers in in the garden, blood loss and traumatised, she promises that she has been assaulted—by Ali’s spouse, Mike. Ali must make a split-second decision: who should she believe? Her horrified husband, or her closest friend? With Mike supplying a very different version of occasions, Ali knows one of these is lying down—but which? And just why?

When the ensuing chaos forces her to re-examine the golden era the group shared at university, Ali realises there are darker memories too. Memories which have lain dormant for many years. Memories someone would kill to safeguard.
