Antonia Scott has an unusually gifted mind, able to see what others miss, able to solve the crimes that baffle all others. The only thing she fears is herself.

Antonia is the lynchpin of the Red Queen project, created to work behind the scenes to solve the most devious and dangerous crimes. But she is unwilling to move past the last case, convinced it's related to a personal tragedy, until a series of deadly events pulls her back in. In southern Spain, in the Costa del Sol, a key mafia figure is found brutally murdered in his villa, his pregnant wife, Lola Moreno, barely escapes an attempt to kill her in a shopping mall and is on the run. A shipping container from St. Petersburg arrives in port in Spain containing the corpses of nine woman, all who suffocated. Now Antonia, with the help of her helper and protector, Jon Gutierrez, must track down this missing Lola. But they aren't the only ones on Lola's trail - a dangerous contract killer, known as the Black Wolf, is also on her trail. And Antonia Scott, still plagued by her personal demons, must outwit, out-maneuver, and, ultimately, face this terrible, mysterious rival.
