Second Chance — Chet Williamson

You are invited to a party. A reunion of old college friends who haven't seen each other since the late 1960s. It should be a blast, with great music and fond memories. But be forewarned, it won't all be good. Two of the friends at the party weren't invited. In fact, they died back in college. But once they show up, the nostalgia will turn to a dark reality as all the guests find themselves hurled back to the '6os. And when they return to the present, it's a different world than the one they left. History has changed and the long-dead friends are still alive--including one intent on destroying them all.
