While I liked this book, I found it too long. It's not a long book, but it's not edited well. It is clearly a wonderful novella wrapped in an okay novel. I'd have liked to see this cut down more; down to its essential core. In the end though, the true test of a book is whether I would recommend it to others, and I certainly would recommend this book to everyone. It has broad appeal, despite its geeky references and Dominican Spanish. I gave it 4 stars, but that's only because I can't give it 3 1/2.
