Author. Purveyor of little clippies. An absolute delight. THE SIDEKICKS, WE COULD BE SOMETHING, OTIS OTTLEY AND THE SCHOOL IN THE SKY.

POSTS STORIES REELS

Otis Ottley and the School in the Sky is available now.

"Kostakis writes with seamless charisma and wit, infusing Otis’s voice with an infectious energy that will keep kids reading (and laughing). Otis’s world is both whimsical and familiar as an everyday Aussie school setting, enlivened by great magical inventions and brilliant action sequences.... An exuberant read, Otis Ottley and the School in the Sky will appeal to kids aged 9 and over who love Tristan Bancks’s humour-driven Tom Weekly books and Jessica Townsend’s fantasy Nevermoor series."

Celebrating October’s Children’s Book of the Month: “Otis Ottley and the School in the Sky” by Will Kostakis ☁️📚

In this funny and warm middle-grade novel, Otis Ottley is an ordinary boy who yearns to go to the magic school in the sky. And he will stop at nothing to make it happen. While many kids dream of roaming the prestigious institution's halls, casting spells and conjuring spectacles, Otis has a very specific mission: to seek magical help remembering something very, very important.

The odds are stacked against him, but Otis will break into magic school. Or at the very least, he will break a few rules trying.

To order your copy, make sure to visit your local QBD Books store or our website via the link in our bio 🔗 by @willkostakis
