Alternative text for cover: Cover of Pretty FaceIsabella Rose is the daughter of Beatrix Rose, once Group Fifteen's deadliest operative, and grew up believing her mother was dead. Mark Dawson's series, launched in 2015 with The Angel, finds Isabella training as an opera singer in Manhattan when the British intelligence officer Michael Pope -- who once ran her mother -- recruits the teenager into the same secretive world, spotting in her the same lethal instincts. The books follow Isabella's development from a talented but untested asset into a genuine field operative, shadowed throughout by the question of whether she's repeating her mother's path by choice or by inheritance.
The series sits alongside Dawson's John Milton and Beatrix Rose books in the same Group Fifteen universe, giving Isabella occasional crossover contact with Milton and other established characters, while keeping its own younger, coming-of-age-adjacent focus distinct from the other series' harder-edged tone.
Six: The Angel, The Asset, The Agent, The Assassin, The Avenger, and Pretty Face.
Yes -- Isabella is Beatrix Rose's daughter, and the series follows her being recruited into the same clandestine world her mother once worked in.
Yes, loosely -- all three of Dawson's Rose/Milton series share the same Group Fifteen fictional universe and occasionally cross paths, though each is tracked separately in this catalogue.
