Query: not bad

well im writing this review for a physics project that i have to do. Well overall i thought the book was pretty exciting. Alot of details were given and the book kept u thinking even at the end when the traveler disapears and never returns. I thought the ending was pretty cook since i would never expect an ending like that. THe book has action, and lots of details. Some parts were hard to understand because of the wierd names that the travler gives but overall the book wasnt bad.
