This is a little CF book a friend of mine wrote a few years ago. I'm afraid it is in Spanish. Should be translated it in the next few years.
It has been read by about 100 people. All of them finished it and said they liked it. So did I. Still, we are mostly the author's friends, so
If you read it, tell me what you think.
The book is in PDf format, specially created for the Sony Reader.
