Meg Grehan is originally from County Louth but now hiding away in County Donegal in the north-west of Ireland, with a very ginger girlfriend, an even more ginger dog and an undisclosed number of cats (none of whom is ginger). Her first book The Space Between won the Eilís Dillon Award at the 2018 Children's Books Ireland Awards. The Deepest Breath won the Judge's Special Prize at the 2020 Children's Books Ireland Awards and was shortlisted for the Waterstones Children's Book Prize. It is published in the USA by Houghton Mifflin Harcourt and in France by Talents Haut. Baby Teeth was a Kirkus Best YA Book of 2022 and was nominated for the 2023 Carnegie Medal.
