operation frog effect is a heart felt book despite its wacky name I would recommend it to 9-11 year olds because one part can be a little scary I am 9 almost 10 and I felt like this was perfect for me the only thing is it only has one Jewish character and she does not show up much

this book was not well done, not well written and not well executed. this book was not good at all personally. I found the title very misleading and as well as the cover picture. This book made me feel frustrated with the characters poor judgement. This book did not have anything to do with frogs which is very very miss leading. Making me think that this had to do with a frog hence the name, Operation frog effect. over all this book was poorly made and uninjoyebell I do not like to give up one books and I always finish books, good and bad. I hade to force myself to read to the end. The book was just bad. Do not recommend

Part is comics which I enjoyed, really nice plot and has a lot of fun at the end

It was ok and very heartfelt

this books is so good I love it. I think I have read it about 5 times by now. Its is such a good book and I would recommend it very much!
