Subtle Blood — K.J. Charles

Will Darling is all right. His business is doing well, and so is his illicit relationship with Kim Secretan--disgraced aristocrat, ex-spy, amateur book-dealer. It's starting to feel like he's got his life under control.And then a brutal murder in a gentleman's club plunges them back into the shadow world of crime, deception, and the power of privilege. Worse, it brings them up against Kim's noble, hostile family, and his upper-class life where Will can never belong.With old and new enemies against them, and secrets on every side, Will and Kim have to fight for each other harder than ever-or be torn apart for good.
