Maeve was born in 1960 in Dublin in the Republic of Ireland and grew up in Redcar on the north-east  coast of England, one of five siblings. She wrote her first novel in an exercise book at the age of eleven. A later version, The Witch King, banged out on a portable typewriter with the aid of copious amounts of tippex, became one of the launch titles of Orchard Books in 1988. Maeve is the author of five more children's books, A Gift for A Gift (1990), Listen to the Dark (1993), A Summer Dance (1990), Midwinter, (1997), and Just a Boy (2001). ​Maeve won her first poetry prize at the age of 15 in a national competition organised by The Observer newspaper and judged by Laurie Lee. ​​Her poetry has appeared in e-publications and magazines including Mslexia,  The North,  inksweatandtears and various prize anthologies.

After reading English at New College, Oxford,  Maeve taught English at a language college. She married in 1990 and has three children. From 2008 to 2013 Maeve worked as a volunteer, and later as a manager, of the detention support programme of the Oxford based charity Asylum Welcome. Currently she works as an assistant data manager at the Haemophilia Centre at the Churchill Hospital in Oxford. She has recently completed a Masters in Creative Writing at Oxford Brookes tutored by Hannah Lowe, James Hawes, Morag Joss and Penny Boxall.
