SAGA
Saga is an epic space opera/fantasy comic book series created by writer Brian K. Vaughan and artist Fiona Staples, published monthly by Image Comics. The series is heavily influenced by Star Wars, and based on ideas Vaughan conceived both as a child and as a parent. It depicts two lovers from long-warring extraterrestrial races, Alana and Marko, fleeing authorities from both sides of a galactic war as they struggle to care for their newborn daughter, Hazel, who occasionally narrates the series.
