The book is okay.
But be prepared to endure the code style writing. The way the author writes his comments inside the code will hurt your eyes and secondly will slow you down in reading the code. A single comment line without the freaking border which surrounds it is enough Kyle. The way you wrote the code just increased the book page number.
I don't know who reviwed your book but next time before publishing something ask for a second opinion from a guy who is not an engineer. IS NOT AESTETHIC !!!
