She has co-written, with her husband John Reppion, numerous comic book stories ranging from tales about sea monsters through to super heroines (Wild Girl). Together with Shane Oakley, Leah and John also produced the excellent Albion. Leah and John have recently seen another of their monsters stories appear in The Dark Horse Book of Monsters.

Leah tolerates John's unhealthy interest in Zombies, and realising that there was nothing that she could do to stop it becoming the theme behind the next Accent UK anthology, has co-written a story to be illustrated by David Hitchcock.
