The Evers

Jack has never used a computer in his life, much less gone to an amazing summer camp. But while he's there, strange things begin happening, and he ends up traveling back in time.
But that's not all.
After the summer camp, he wakes up in a strange room and discovers that he is an 'ever', a person who can do magic. But nobody expects things to go horribly wrong on the first day. . . .
