Gwyneth Rees was born in Leicester in 1968, and moved to Glasgow at the age of six. She studied medicine at Glasgow University and qualified as a doctor in 1990. She now works as a child and adolescent consultant psychiatrist and has lived and worked in various places, including Birmingham and London.

Gwyneth's interest in writing has been constant since her childhood when she was an avid reader of Enid Blyton and wrote her first "book" in an exercise jotter at the age of ten. (It featured four children trying to solve a mystery about sheep rustlers on the Isle of Skye!) As a medical student she went on writing workshops during the holidays, which fuelled her desire to be published.

Her first children's novel, SOMETHING SECRET, was published in 1995 and since then she has added three titles in the MERMAIDS series, MERMAID MAGIC, RANI'S SEA SPELL and THE SHELL PRINCESS; a novel for 9-11s, THE MUM HUNT; and for 7-9s, FAIRY DUST, which was an Ottakar's Book of the Month choice. In order to find the time to write, Gwyneth now works part time as a doctor and spends the rest of the week on her novels.
