Sea of Silver Light is the concluding chapter in the Otherland saga and I have to say it wasn't as good as the first three books in the series. I still enjoyed it but something about the way it ended just seemed kind of hollow and lacking to me. I don't want to spoil the storyline so I won't say anything more about that. What I will say though is that the Otherland series is great as a whole. The story is cool and shows a very believable not too distant vision of our world, the net's place in it, and how our lives will be permeated by the incredible levels of access to information we may all have someday.
