When Mase Winslow, the heir to a Civil War-era plantation is forced to almost kill his best friend, a slave named Spoon, he unconsciously brings about the demise of his beloved home. As guilt and remorse overtake him, he seeks atonement through death on the battlefield. With the help of an ordinary-looking stone given to him by Spoon’s mother, he is transported through time. When he realizes he can redeem himself by altering his actions, he suddenly has hope. The reality-bending journey that ensues takes him to present-day New York City and then back to Civil War-era South Carolina, requiring him to navigate a myriad of desperate challenges. With more than a century of guilt weighing him down, he battles himself, Yankee troops, nature’s elements, and a nemesis that follows him through time. Set against an ominous ticking clock counting toward a deadly showdown that could cost him the love of his life, all odds are stacked against him.

After Mase Winslow travels back in time to post–Civil War South Carolina, he leaves behind his friend, Zoey Antonelli, to deal with the harsh realities of modern-day New York City alone. What he doesn’t know is that he’s also leaving her with the constant reminder of a hidden love she harbors for him. Rather than fading, her feelings continue to grow over the next ten years, gradually pushing her toward an emotional cliff that could destroy her. As she struggles with the regret of not professing her love while he was present, she turns to a journal Mase left her. From its pages, she attempts to piece together an implausible life that would reunite the present with the past. It is only when the power of the memory stones comes into play that such an impossibility becomes reality. Using the stones, and with love as her only objective, she sets off on a journey that will not only redefine what true love really is but also highlight the difficulties we must sometime endure to achieve it.

A century and a half after the memory stone first transported him through time, Mase Winslow is once again subjected to its mystical powers as he is pulled from the love and safety of his Willow Creek plantation to come to the aid of his friend Zoey Antonelli. Along with her new love, Boone Vanderson, they have been thrust forward in time only to be separated along the way, deposited onto the cruel streets of New York City. Stripped of her memory and without him having any knowledge of the twenty-first century, they struggle to survive. Death and destruction loom as a demon from their past joins forces with a villainous element in the present. With greed and revenge at the heart of this unholy union, Zoey and Boone's lives hang in the balance. The saga of the Winslow family and all those they love comes full circle as the memory stone reunites them in a battle of good against evil where true sacrifice is the only means to prevail.
