Plenty has been written about daily life in mediaeval times - Robert Lacey and Danny Danziger's The Year 1000 stands out, while SJ Parris and CJ Sansom are two who have brought the late mediaeval ages to life in detail in historical fiction - but little enough of it relates to Ireland. Dwyer's book is a welcome exception in that regard, focussing on daily life in 13th and 14th century Ireland.
One problem, acknowledged at the start, is that one reason there hasn't been much written is that there unfortunately isn't a huge amount of source material to draw on. Most of the windows opened here relate to the Normans, and the native Irish usually feature either when fighting, or being hanged by, the Normans, who were at this stage far from being "more Irish than the Irish themselves". Surnames such as Freysel, Cachfrens, Suerbeer, Cuanteton and Madoc feature far more often than O'Ryan or O'Byrne, giving the past an unexpected feeling of being a foreign country.
This, of course, means the material is heavily skewed towards the wealthier sections of society, with some bits on the urban poor and almost nothing about the majority peasant class. There is a feeling at times that Dwyer is stretching his anecdotes out as much as possible, and that the seven pages on food in mediaeval Ireland is close to all that's known on the topic. But there's quality there, if not quantity - the poor often lost teeth because they couldn't afford bread without bits of stone in it, while the rich could spend a peasant's annual salary on a single slap-up meal.
A minor criticism is that measures, particularly of money, could be better explained. We have pounds and marks (what's a mark?), a theft of goods worth five shillings 12 pence (is this not six shillings?), annual salaries of 60 pence (is this not five shillings? Or did the £ s d system differ to later centuries?), while crops are sold by the crannock (but it's not clear what a crannock is).
But if Dywer doesn't quite succeed in creating a Technicolor image of his subject, this is definitely a book better put out than held in, and well worth the read.
