I just finished Looking for Alaska by John Green... What did you think of the book?

Do you think she killed herself, or was it really just an accident? Or was it a heat of the moment impulsive action she was so prone to making? Also, what do you think of Pudge's relationship with Alaska? Was it true love or just an ignorant infatuation? Do you think she loved him back, or did she just like the attention? What do you think about the labyrinth?
