Gur Shomron's NETfold is a really cool book. If you enjoy sci-fi adventure, this should be on your summer reading list. I would recommend it to those who enjoyed Caprica the tv show or the Ender's Game books.
In the Net, there is a different world with different rules. It is fantastic in it's technological imagery. While at times, it jumps around in a manner that takes full attention to grasp, it's easy to immerse yourself in the virtual nature in this daring science fiction book.
You should definitely grab a copy.
