This was the first time I tried the "easy to read" style of diet cookbooks and for me, it's a big drawback. The book is very small so when you have pages turned to look something up, it is difficult to read because light from my Kindle Reader would make any page hard to read. It seemed like if there were different colors on each page, then maybe these would be easier to read, but they didn't do this either.
Bad review
