Mae trigolion pentre dychmygol Pantglas yn wynebu newid byd wrth i’r gwaith mawr ar yr argae ddigwydd o’u cwmpas. Symud fydd eu hynt, ond cyn hynny bydd llawer o ddŵr wedi mynd dan bont eu bywydau. Nofel egnïol sy’n defnyddio peth o hanes Llanwddyn a Llyn Efyrnwy fel man cychwyn i ddychymyg byrlymus Mihangel Morgan. Adargraffiad; cyhoeddwyd gyntaf yn 2011.

A new era is afoot for the inhabitants of imaginary village Pantglas as major work to the reservoir takes place around them. They will have to move, but a surge of water will have passed under the bridge before then. A lively novel which uses some of the history of Lake Vyrnwy and Llanwddyn as a starting point for Mihangel Morgan’s riotous imagination.
