This is my second year of teaching 5th grade, and both years I've used this book in Language Arts. The kids LOVED it, both years we've read it. It's also a breeze to pull out spelling words and vocabulary words from.
The kids can totally relate to Gib, his relationship with Ash, Rainy, his little sister, and of course, the dreaded 'Ol Shrapnel. The book has the kids' attention the whole time, and it's great to be able to watch my students actually WANT to read and see what event is going to happen next. I even caught a few students who just HAD to read ahead.
I'd say that this book is a classic for 5th and 6th graders, and my students and I would love to see it made into a movie soon! A+

Gib realizes that the odd machine he was given by a strange old man may hold the key to undoing the most devastating day of his life. He quickly learns, however, that there are consequences for every single action, however insignificant they may seem, and that trifling with such power is a huge responsibility. Who WAS that old man, and why did he seem to have such an interest in Gib and his family?

Etchemendy has done a brilliant job of leading the reader to consider some questions even larger than, "What would you do if you could travel across time," or "If you could change an event from the past, what would it be?"

Gib Finney is not your average kid. He is a kid who likes to cause frustration at school by shooting spitballs at people and messing around with science experiments. But soon he finds a device that can change his life forever. He can erase all mistakes he has made in the past with this device. But then there is a terrible disaster that he can not erase no matter what he does it will still be there in some way. Then he has to find out what mistakes are worth erasing and which ones are not. I thought that this was a really good book. You should read it too!

This book is very enchanting, intriguing, and mind-gripping. The stories that it holds are very- oh- well, scary. If you want a good scare, then this is the book for you. I actually don't own this book; I got it out of the library for Halloween. This book is very intriguing, but not for people who are easily scared. Overall, this book really isn't gross and gruesome, unlike some other mystery novels. I give this book four stars.
