Query: Couldn't put it down

Although on the surface a book about unpleasant subjects (death, alcoholism, lost loves, and the impact of war), Charming Billy is really about friendships, love, and caring. It touches on the subjects of the Irish and Catholicism in a non offensive way. Although the author's style of inserting quotes in the middle of sentences without proper punctuation was a bit difficult at times, this aggravation was far outweighed with writing which at times is nothing short of brilliant. Pick this book up and you'll not be able to put it down until you are finished.
