This book is decent, I guess, for a general overview of early Irish history, but it should be taken with many, many grains of salt due to the author's complete lack of criticism of Roman sources describing Celtic society. Chapman also glosses over certain aspects of Celtic mythology, especially in regards to the Morrigan, completely ignoring that Macha is one of the three Morrigans and omitting the reason for Macha's curse on the men of Ulster. Definitely will look elsewhere for more, more detailed, and more accurate information.
