1963: What would you do if you had the ability to change the course of history to reunite with a loved one? Would you commit treason and risk a lifetime in jail to accomplish that mission? For Dr. Michael Shriver, NASA scientist, that opportunity was about to fall into his lap, until three teens from New Haven, Connecticut crossed his path and TIME itself began to spin out of control. Fifteen-year old Ace Roberts and his friends Debra and Brian take you on a fantastic journey across the fourth dimension in this third outing in the Young Ace Roberts adventures - BACKSPIN.
