A former assassin, battling her demons. A sinister enemy, determined to destroy her. A wily street kid caught in the middle. Former assassin and SHEN operative Leine Basso is fresh off an assignment rescuing an American teenager from a terrorist group in Libya when she thwarts the murder of a street kid in Tripoli. Leine agrees to help the girl find her family, but must first visit a refugee camp in the desert where there are disturbing reports of mysterious abductions. Leaving the camp, Leine comes under a surprise attack-but only a handful of people knew her true mission. Who has betrayed her? The more she discovers about the abductions, the more of a target she becomes, forcing her to revisit a dark and violent past she thought she'd left behind. But it's easy-too easy-to fall back into the old ways. And that could get her killed. Will Leine be able to survive a dark return?
