Catherine Doyle was born in the West of Ireland in 1990. She holds a BA in Psychology and an MA in English.

As a child she was an annoying smarty-pants with an overactive imagination. She feels lucky to have now found a healthy outlet for her tendency to make up stories.

Her debut YA novel, Vendetta, is the first in a trilogy. The novel takes place in modern-day Chicago, where Catherine’s mother grew up.
