Eve Dallas is a homicide detective in New York of the 2050s, assigned to investigate the murder of a senator's granddaughter. Roarke is a self-made Irish billionaire. He is also a suspect in her investigation. Eve ignores every warning to not become involved with a suspect, and does something she has never done before: trust.
Each book in the series can be read as a standalone. Read in order, however, you get to witness the growing relationship between Eve and Roarke, and the growing cast of characters who become important to them both.
