Renna Nightingale

Excellent writing! As a non-tech person, I was nervous to read this book, but wanted to expand my horizons. I was pleasantly surprised how accessible it is! There is wonderful metaphorical language to help “tech muggles” like me grasp foreign concepts. This book is very well done and can help beginning and advanced coders alike. Well done!
