Colm gets called 'Colin' a lot, and sometimes 'Colon'. He doesn't help himself by mumbling his words a lot of the time, except in his job as a builder, when he winds up shouting instead. He lives in London with his three kids, who he baffles by both mumbling and shouting, and his partner, who somehow understands him without the need for either. Colm is happiest when he's excitedly writing a new story on his rusty old phone. His favourite mode of transport is walking, so obviously he's the perfect person to write about high-speed multiverse-hopping on everything but feet.

Colm's middle grade debut is due out in 2024.
