For some odd reason I am drawn to books about teenagers struggling with life and death and 'If I Stay' is a perfect example of this kind of book. I particularly enjoyed the structure and the explanatory format of cutting back and forth between the past and present to advance the story. This is often annoying in other books but 'If I Stay' employed it effortlessly and beautifully. Forman's anecdotes were also a perfect example of how to write by 'showing, not telling'.
I've noticed other reviewers complaining that the characters are cliched which is true, in a sense, but I believe it was exactly these character traits that made the book so likable.
I can't say this affected my outlook on life as it has others but I really enjoyed Forman's style of writing and even though the premise of the sequel doesn't sound all that enticing, I'm looking forward to reading it for the writing alone.
