Oíche stoirme a tháinig Dónal agus Éamonn chun an tsaoil, ach más cúpla féin iad, ní hionann ar fad an bheirt deartháireacha seo. Sa léann atá dúil ag Éamonn, ach is fearr le Dónal a bheith amuigh ag iascaireacht. Is iomaí cor a bhaineann dóibh féin, dá muintir agus dá bpobal go mbeireann oíche stoirme eile orthu. Insítear a scéal go gleoite sa leabhar seo, a tharraingíonn ar an chuid is fearr de thraidisiún úrscéalaíochta na gConallach.
Dónal and Éamonn were born on a stormy night, but even though they were twins the two were not a bit alike. Éamonn is interested in education, but Dónal prefers to be out fishing. In the best of storytelling traditions the author describes with gusto the many adventures, some of which were on very stormy nights, the twins and their family had.
