I thoroughly enjoyed Rachel's Holiday by Marian Keyes. First of all, the depth of information it gave about addiction was astounding -- Ms. Keyes really seems to have done her research. I don't see how anyone could become an addict after reading this book!
What I especially found interesting was the dichotomy of Rachel's viewpoints -- she thought one way while she was still abusing drugs (and when she first started at the treatment center), and a completely different way when she began to recover. There were people she considered "stingy" or "no fun" while she was abusing drugs; she later realized they were only trying to help her. On the other side of the coin, there were people she used to think were almost godlike, and she finally realized that these people were human just like her -- and not really as great as she originally made them out to be.
Above all, though, I found this book entertaining. Marian Keyes has a wonderfully wicked sense of humor that I can truly appreciate. I'm starting to figure out that I really like books told in the first person; this book and Lucy Sullivan is Getting Married (which I read first) both drew me in with their cozy girl-talk style. I know this is a major cliche, but I really did not want to put this book down -- I felt so involved in everything that was happening to Rachel.
The only problem I found with the book is that I thought the ending was a little too convenient and a tad too predictable. Anyone who read it kind of knew how it would end about a quarter of the way through the book. That in itself was not necessarily so bad; to me, a lot of the enjoyment in a book is watching the journey from point A to point B, even if you already know what point B is. (This is a key philosophy to keep in mind when reading romance novels.) However, it seems to me Rachel should have had to work a little harder for that outcome than she actually did.
All in all, though, it was a very pleasant, worthwhile read, and I'm looking forward to reading more of Ms. Keyes' books.
