Liam was born in Northern Ireland and came to Canada when he was five years old. He studied media at Ryerson University and has worked on film sets in Canada, Ireland and the United Kingdom.

He left the movie industry in 1999 when his first book, System Shock, was published by A & C Black in London, UK and has been writing ever since.

He has also developed educational radio plays for the BBC, written articles for adults and children for numerous national magazines, adapted TV scripts for Kids Can Press, and created original comics for A&C Black Publishers, Owl Magazine, Scholastic Canada, Stone Arch Books and Capstone Press.

He is represented by Marie Campbell of the Transatlantic Literary Agency.

In addition to writing for young readers, Liam is an elementary teacher, currently helping kids find knowledge (and lost books) in Toronto. He is also a founding member of GamingEdus, a group of educators messing around with multiplayer worlds. Currently, Liam’s students are blowing up stuff on the Multi-School Minecraft Server, he created with his GamingEdu pals.

Before all that though, Liam delivered hot food in restaurants, cold tea on movie sets, slimy fish in Dublin, bottled water in Vancouver, and bad jokes in theme parks as a professional juggler.

Liam lives in Toronto, Ontario with Melanie McBride wired writer, educator, rock star academic, wife and best friend.
