Wanting something different, I picked up this story wanting an adventure. Instead, I got a story that really didn't capture me the way I expected it to.The plot of the book really confuse me in the beginning. Things weren't really explained to the reader and I was lost for a few chapters. I found myself re-reading passages just to make sure that I didn't miss anything. I decided to keep going, hoping it get better. It did, but it still left me with lots of questions. I did continue reading but found myself getting well a little tired of feeling lost.Half-way through the book it gets better. Finally things are coming together and I'm finally getting the picture. I like the idea of people's chemistry/DNA changing due to some catastrophic event. It's like some stayed the same and other just were changed completely. The twist with the main characters Jack and what happen to his parents is the highlight of the book. It had me wanting to know why such a drastic change???Of course by now you know that my gripe is that the book is really slow and hard to understand in the beginning. After a while, the reader is able to get it and the ending is quite good for such a slow beginning.London Eye is a good book with potential. I can see that the ending is really good, that it is something I want to read more of just cause I need to know what happens next. Hopefully the next book will fulfill my adventure.
