Timestorm Riders

The 8 brothers and sisters of the Vann family struggle to become Longtimers, Members of the Society of Time, a community of people who take Shelter during Alterations in the Past so they can Survive Changes in recent history with their memories intact. They must survive for another three and a half Seasons (just under six months) and pass a Membership Exam, but to do so they must endure the dangers of Timestorms, clueless Bystander, Time Criminals, crazed Longtimers, the Fourth Dimension, and most of all their own stress and uncertainty. Will they make it--or will they have to start all over again with no memory of the Time Travel World or their recent struggles in it?
