This was a gripping thriller told from multiple points of view. The story starts in the present day with the upcoming wedding of Adele and Jason on the sunny Australian coast. The wedding  location is one they are all familiar with. Unfortunately, their mutual childhood friend Ollie (Adele's ex-boyfriend) had a tragic accident in the jetty there a decade before, and this dark event is still impacting their lives as the wedding approaches. 
The story is narrated by Adele and Melanie (Ollie's mum) and the chapters alternate with Sophie's story of the events leading to her brother Ollie's death. 
It took me a little while to get to know all the characters, and I did occasionally need to double check the narrator but I loved the slow build up of suspense and feeling of impending doom as the wedding day approached. 
There were a lot of hidden secrets and interesting back stories connecting the central families. I raced through the final part of the book as I really wanted to know if someone was going to be murdered and by whom? I also wanted to know what had happened on the night in question with Ollie all the years  before. A very entertaining read!
