Anna is a captive, a possession, a whore, whose freedom is within reach only to be brutally snatched away under the guise of protection. Rafael D'Cruze, a man Anna despises and fears, has become her captor, yet she finds an inexplicable sense of safety in his presence. Anna is a 'sweet collateral,' a pawn in a dangerous game of debt and protection, but Rafael finds himself increasingly drawn to the 'little slave,' willing to risk everything for her trust. Their relationship is a volatile mix of hate and longing, a dangerous dance between a broken bird and a wolf that could lead to healing or destruction.

This collection, comprising the bestselling Collateral series, is characterized as a dark cartel romance. The narrative appears to focus on the intense, often fraught relationship between Anna, a captive, and Rafael, her captor, exploring themes of power, desire, and the blurred lines between hate and love. The premise suggests a story that delves into the psychological complexities of their situation, with a high degree of emotional intensity. Readers can expect a narrative that navigates the dangerous world of cartels and the personal stakes involved in such a setting.
