I just finished this and enjoyed it very much. I love the whole "someone does some crazy feat" genre -- I will totally read Diana Nyad's book should it ever come out. This book kind of makes me want to build a little boat and to idle around, though I have no desire to cross an ocean.
PS. Gentle reader, don't get hung up on the word "love" as many reviewers here have done -- and if you do, just take a moment and think of the many things that love can and does mean.
