I don't dole out 5-stars very often, but this one is deserving. Awesome read, incredibly poignant and life affirming. I think Green really earned what he had to say, which so many authors don't bother to do.
Alaska was such a fire-cracker of a character, but I think he did her great justice. I love how he structured the book, with the before and after. It somewhat prepared the reader for her accident/suicide, which, if it had come completely out of the blue, would have felt contrived. The middle of the after portion got a bit repetitive (a few of the ideas were rehashed every few pages, like POOF), but it would have been too easy to brease over the after bits.
