Three days. One impossible choice. During the COVID lockdown, Michael Walker is desperate—out of work, drowning in debt, and running out of time. When he volunteers for a medical trial that promises fast cash, he expects a mild side effect. Instead, he wakes up in 1970. Stranded fifty years in the past, Michael quickly realizes he holds something far more dangerous than knowledge of history: the ability to rewrite his future. With the right investments, he can secure wealth, safety, and freedom when he returns to his own time. Then he meets Diana. Brilliant, enigmatic, and impossible to read, Diana draws him into a world where time feels fragile and love becomes the one variable he can’t control. What begins as a plan to survive turns into a connection that threatens to undo everything. Because three days are not enough to change the past— but they may be enough to decide what kind of future is worth living. Three Days is the first book in the Rewind Trilogy, a time-travel novel about love, regret, and the cost of getting exactly what you want.
