I expected it to not go very in dept about any part of Ireland's history, since it's subtitle is "A Concise History from the Twelfth Century to the Present Day". I think this one was a little too concise. I don't think I've read a history of a entire country before, even one that spans less than 1000 years. The history books I read tend to focus on one point in time (like Elizabethan England) or one person (like Catherine the Great), so maybe this concise overview is standard.
I did like the book, it was easy to read and didn't confuse me with a lot of dates. I don't know that much about Irish history, so I felt a little lost at some points and that's the main reason that I'm a little annoyed with the whole concise thing. I didn't really think about what that would really mean until I downloaded the audiobook and it was only 8 hours long! I've read novels that have been longer than that!
I feel a little unfair, since the subtitle should have been a give away, but it seemed like too much time span for such a short book. It was a good general overview, but I still feel a little cheated, somehow.
