The Accidental Adventures of Onion O’Brien

The deadly children’s debut from Ireland’s Got Talent’s Jason Byrne!

Meet Onion O’Brien. He’s an ordinary kid growing up in the suburbs where nothing ever happens. Except when it does, it always happens to him.

Luckily, his friends have his back. There’s Sive O’Connor, Dallan Okoye, Cliona O’Hare and Onion’s big brother Derek (who thinks he’s too cool to be in the gang). Together, they’re the Five O’s.

For his birthday, Onion is taken to the circus, where a baby ape manages to find her way into Onion’s backpack. Can the Five O’s save her from the evil ringmaster and keep her hidden in suburbia long enough to get her safely to Tota Island Park?

Inspired by Jason Byrne’s own accident-prone suburban childhood, this is set to be one of the most exciting debuts in children’s books this year.
