I personally had fun going through Build Your Own Lisp and learned quiet a lot. I really liked the writing style and images. That said, it is not a good good way to learn neither how to write a Lisp nor how to use C the proper way. Some of the stuff is very idiosyncratic or even questionable. Again, for me it was fine because also used other sources to complement it and it got me interested and thinking about various topics. Just beware that it teaches things that will hold you back if you ever became serious about implementing a Lisp that is more than a toy. If you already quite OK with C and don't need much hand holding I would suggest going through MAL instead.
