Back in the Day

In the year 2253, the government decides what job a person will get depending on his/her high school grades. Keelie aspires to be a teacher, but her grades say 'scientist.' When the government starts killing off the slackers, starting with her best friend to make an example, Keelie decides she must step in. Oh, one thing about Keelie. She can time travel, only she can't control it. She gets about a ten second warning before she disappears. She teams up with a group of other 'special' people and together they find out the dark truth about their country's past and about themselves as well.
