Best Book To Start Unity?

Hello! I was wondering about the best book to start learning Unity, I don't know one line of coding, I have heard of
Unity Game Development in 24 Hours
And I was wondering if that was the best to get or if a different one will be better?

 

This is the book I’m reading and try to learn Unity. I’m in the “Hour 3” of the book and so far I can say I’m pleased with the way it is written. I’m stuck however, in one of the exercises and I don’t know how to proceed. I have posted a question here at the forum but so far nobody has helped me. Apart from that I can say that the book is well written with simple instructions that can be easily understood.

 

I acually might get this book, http://www.amazon.ca/gp/product/146...pf_rd_t=101&pf_rd_p=1947489602&pf_rd_i=915398
