Will Kostakis, award-winning author of The First Third, perfectly depicts the pain and pleasure of this teenage world, piecing together three points of view with intricate splendour.

The Swimmer. The Rebel. The Nerd.

All Ryan, Harley and Miles had in common was Isaac. They lived different lives, had different interests and kept different secrets. But they shared the same best friend. They were sidekicks. And now that Isaac's gone, what does that make them?

'Gutsy, ambitious, funny, sad and beautiful.' - Melina Marchetta, Printz Award-winning author of Looking for Alibrandi.


The Sidekicks is a hypnotic story of friendship, loss, grief, self-discovery and most of all - love. Read this book. Trust me. I loved every word and you will too.

Jennifer Niven, New York Times bestselling author of 'All the Bright Places' and 'Holding Up the Universe'

Kostakis makes good use of the three characters' narratives, moving from relatable Ryan to sympathetic Harley and finally the initially unprepossessing Miles, whose inability to wear a social mask and habit of seeing his life as a movie make him a touching narrator.

Publishers Weekly

While this is Kostakis's American debut. his literary polish and deep understanding of teen storytelling is compelling and nuanced from the first page ... A memorable experience with teens who grow to absorb tragedy and build a future on its foundation. VERDICT - An excellent exploration of grief from a rising talent that belongs in al libraries serving teens. (starred review)

School Library Journal

A masterfully written story filled with heart, sorrow, and hope.
