Complete story — includes the ending
Cole and Cassie travel to 1944 to stop two of the Messengers from murdering a scientist, Thomas Crawford. They are unable to prevent Crawford's death but deduce that the Messengers' real target is his son Tommy Jr., who, like Jennifer, is a "Primary" with a special connection to time. They manage to get to Tommy first; he addresses both of them by name and says he is fated to be killed by the Messengers. One of the Messengers takes Cole hostage and tortures him, forcing Cassie to surrender Tommy. The Messenger kills Tommy in a ceremonial ritual using bone taken from his remains in the future, triggering an explosive temporal paradox that renders her, Cole, and Cassie unconscious and strands the latter two in 1944. In 2044, Jones allows Deacon to do as he wishes with Ramse. Just as he is about to kill Ramse, a massive temporal anomaly erupts, and Ramse runs to escape it, dragging Deacon along with him.
