The inseparable are well and truly split.

Mack, Faith and Lacey, joined at the hip since primary school, are about to graduate high school. You might think this sounds like a book about coming-of-age and taking that leap into adulthood.

It is- except one of them doesn't make it …

Lacey Marone had two solid things on her agenda for her future - working in the Pepperoni Palace until she figured out what the hell to do with her life, and getting together with her bestie's older brother, Quade, who she's crushed on since she was a kid.

Then graduation night changed everything. Almost three years later, Lacey won't rest until she discovers the truth surrounding Faith's death. She's outcast by those who want to move on from the tragedy, as if the town's sweetheart never existed.

Years after losing Faith, Quade Kelly returns home to Runaway Beach, determined to mend ties with his parents and cement a future in his hometown teaching at the local primary school. Quade soon learns that his sister's ghost lives on, thanks to Lacey, the girl who still owns a piece of his heart.

Lacey is hung up on her quest for answers. Quade wants to bury the failures of his past. The pull between them can't be denied but can the past be forgotten?

Truths will be uncovered and hearts will be cracked open wide. After all, graduation was never meant to end like this.
