I have recently become a fan of dystology. After reading The Uglies series I needed something to fill the void. Unwind, so far, has been it. I will admit I did not love the beginning of the book. There are a lot of characters and I couldn't always remember all the details. I felt like I needed a score card and did go back to the first book to see what they were talking about since we are very, very briefly given an incident in the first book that we are given more information about in this book. So, I found the first 100 pages or so (I have the Kindle version so not real sure) not all that exciting.
That said, as I read further, the book took on a new life of it's own with character surprises and details that were introduced and then explained later. I like surprises when I read and this book had a number of them.
There were things in the book I didn't care for. The writing itself was sometimes briefly annoying. I also didn't like the character of Starkey. Other brief parts just didn't seem to make sense. Those parts may be cleared up in the next book.
Alll in all, I really enjoyed this book. I finished it last night and have already downloaded the next book in the series. If you liked Unwind, I think you should read this one!
