Sinopsis del Libro

Although no one knows, the Time Guards exist: a group of youths responsible for resolving anomalies in history. To do so, they travel into the past moment and place to correct them. However, as the anomalies grow, the agents work relentlessly, risking themselves further to discover what is creating them. Laura, the newest agent, has persistently pushed herself to fix the past so that history can continue as we know it. Because if one detail is altered, it could unleash the Elephant effect.
