Redeemed

Redeemed by Margaret Petersen Haddix, 406 pages

“Jonah was able to save all of time from collapsing but in doing so gained a twin brother, Jordan, who must learn what has happened and do his own part to save time--and his parents.” I enjoyed the end of this series a lot.  The entire series was fun but the books really should be read in order.  Kids who like science fiction will love this.
