Patricia Lynch is best known for The Turf-Cutter's Donkey, first published in 1934. This story concerns Seamus and Eileen, an enchanted teapot and the little grey donkey, Long Ears. The children meet a leprechaun, a golden eagle, the Salmon of Knowledge and Finn on their adventure. A few sequels followed.
Another series of hers is the Brogeen series, a fantasy children's book series. In this series, Brogeen is the name of the main character in the book, a leprechaun who keeps running away from his home. It has been read on radio and released as a puppet theatre series on Irish TV.
The Bookshop on the Quay is her best-known non-fantasy book. It tells the story of Shane from the country who learns the trade of bookselling at The Four Masters Bookshop in Dublin. The book was read on Jackanory.
Lynch's literature, always morally simple, remains praised for its otherworldly depictions of life in the west of Ireland. Her protagonists often encounter characters from Irish folklore, and speak a Gaelicised English reminiscent of Lady Gregory's Kiltartan.
Marcus Crouch in The Nesbit Tradition describes Lynch's work as "the richest and most heart-warming of family stories." He particularly mentions the fantasy The Grey Goose of Kilnevin and the "homely adventure" Fiddler's Quest.
Her works had many different illustrators, including the renowned artists John Butler Yeats (The Turf-Cutter's Donkey) and Sean Keating (The Grey Goose of Kilnevin).
