Tony Solomon never wanted to be a time traveler. But when a freak accident gifts him with the ability to travel in time, he becomes an unwilling initiate in the Saturn Society, a secret society of time travelers. Determined to prevent his daughter's murder, he violates the Society's highest law and becomes a fugitive. But the Society refuses to tell Tony how to time-travel within his own life, so he seeks help from Charlotte, the woman whose life he saved during a prior trip to the past. When Tony arrives in 1933 looking for answers, Charlotte is both thrilled and terrified to see her childhood hero. Loyal to the Society, she is honor-bound to bring to justice those who manipulate time for their own gain. In giving him sanctuary, she faces a terrible choice-condemn the man she loves and to whom she owes her life, or deny her deepest convictions by helping him escape and risk sharing his sentence.
