What I Know About You is a heartbreaking tale about a family and an impossible love, torn apart by secrets and traditions in late‑twentieth‑century Cairo. As a boy in 1960s Cairo, Tarek grows up knowing his life has already been laid out for him: he will become a doctor like his father, marry, and raise a family. Under the close watch of his mother and sister, he begins doing exactly that — until Ali enters his life and turns it upside down.

The two men, from very different worlds, embark on an unsayable relationship that threatens to tear apart Tarek’s family. Years later, now living a solitary life in Montreal, someone begins writing to him — piecing together a past he desperately wants to forget. But who is the writer? And will Tarek uncover the truth in time?
