I was going to give this book two stars until I got to the last third. Though the writing style is similar to how a modern teenager would speak and is written well. There didn't seem much point to the story and I after a few incidents on the island I found it hard to sympathise with the narrator, as he does act incredibly selfish while on the island.
The last third of the book gained that extra star as the character does start to become less selfish as time on the island goes on. And after the characters find out that the plane crash did not happen by accident but was in fact staged and their time on the island is being documented, then they do all work together to get off the island.
The book is quite a quick read and easy to follow. It's just a shame that the last third of the book is the only part where I enjoyed the story and characters.
