Sophie has spent her entire life being treated like she is worthless. After years of abuse at the hands of her adopted family, she finally gets the chance to escape when they offer her to ruthless Italian mafia boss Nico Moretti as collateral for a debt they cannot repay. With the Russian mafia repeatedly attempting to assassinate him, Nico refuses to let their attacks push the Italian and Russian mafias into another war. Instead, he decides to turn Sophie into a weapon and send her after the one man he cannot kill himself. But training Sophie is harder than expected. As she learns to manipulate, fight, and survive in Nico’s dangerous world, she also begins to break out of the shell years of abuse forced her into. And somewhere between their dangerous missions and months of training, the ruthless mafia boss begins to see her as more than just a weapon.
