My biology teacher assigned my grade a project, make a model and present it to her, or read a book. We had an option of three books. I chose this one. I'm sure glad I did! I loved it! Everyone is saying its long... its not that long, only 380 pages. Although I would say the author could have ended it a lot earlier than she did. I was thinking halfway through the book that it could almost be done, what else does she have left to say? but all in all its a great book! READ it!
