"But, Alex, tell me, how am I supposed to think about time without, consequently, invoking the machine to go back?" In a letter to the long-lost love of his teenage years, a Peruvian man living in Germany finds himself revisiting the months he and his recipient, a fellow student named Alex, spent together during an exchange in northeastern Germany in 2016. As he reflects on their encounter, he must also confront the brutalities that surrounded their time together. As Javi, the narrator, writes the letter during his journey to the airport to fly back home for Alex's mother's funeral, he uncovers his relationship with the burdens imposed on him by his conservative upbringing, forcing him to face the way he was taught to relate to shame, religious guilt, violence, love, and most importantly, his quest for liberation. Sons of Time and Sin tells the story of the comfort in memory, and the ways in which the past has the capability of imprisoning just as much as it is capable of freeing us.
