For some reason when I finished this one, I got the old Pink Floyd lyric stuck in my head: "We're just two lost souls swimming in a fish bowl."I could understand Allie's anguish at the beginning, but not her guilt. But then you find out why and it a lot of it makes sense. And then you find out more, and you are kind of amazed at how well she has been keeping it together.Colin was very hard to understand. We knew what Allie was thinking, but we never quite knew what he was thinking until the very end. And that actually made sense, too.I really think there is plenty of room for a sequel - not for our main characters who still have a lot of things to figure out in the end - but for some of the people around them.
