Mo O'Hara is the author of the My Big Fat Zombie Goldfish series.

She grew up in Pennsylvania and now lives in London, where she works as a writer, actor, and storyteller, visiting theaters and schools all across the UK and Ireland.

Mo currently has not one, but TWO epically bite-y and mostly evil kittens of her own (true fact).

Loretta won the Waterstone’s ‘Picture This’ competition in 2012 and has since illustrated numerous picture books including Beauty and the Beast by Michael Morpurgo, A Monster's Moved In by Timothy Knapman and the Sky Private Eye series of picture books by Jane Clarke.

Loretta has also illustrated several young fiction titles including the Dougal Daley series written by Jackie Marchant. She lives in London with her husband and pet hamster, Torben Redbeard.
