Today’s Welsh word, for readers of ‘Not Thomas’ who aren’t familiar with the language, is duw – which sounds like what you might find on your lawn in the morning. It means ‘god’.

On page 86, when Tomos is the only one left without a bacon butty, the fair-minded Saint says: “Duw, you’re a heartless cow, mind Ree.”

And it’s often said twice after hearing a surprising piece of news, for example:

“Mammy turned up for the Christmas concert.”

“Duw, duw.”

Sara’s debut novel ‘Not Thomas’ – a story of child neglect, love and hope, shown through the eyes of five-year-old Tomos – is published by Honno Press in paperback and as an e-book, and is available to buy direct from the publisher, from Amazon and from all good bookshops.
