Lying About Last Summer by Sue Watson

Skye witnessed her sister Luisa being murdered poolside at their old house last summer. This summer, she is returning to a nearby grief activity camp for a week to try and move on and accept her sister's death.

All she knows is her sister was in a relationship with Nico, a bad guy and a drug user whom didn't seem right for her unlike their old farm shop working friend Toby.

At the camp, she discovers creepy Joe who seems over friendly and too controlling who's girlfriend committed suicide. Meanwhile she befriends Brandon, Fay and Danielle.

As time wears on, Skye starts to receive messages supposedly from Luisa on their messaging app only something somethings seems off as Skye realises it can't truly be her, can it?

So Skye sets off investigating all those at camp with her, from drug takers and old friends, before a final explosive near death this book may start slowly, but the investigation culminates in a satisfying way for sure as a minor plot also overtakes the original one. I found by the end I was thoroughly satisfied with a nice quick mystery thriller and Sue has a couple more you should check out as well if you like this one!
