Agent Black is the perfect agent-skilled, precise, and painfully by-the-book. Agent Red is a walking disaster-reckless, unpredictable, and allergic to following orders. Their first mission together? A complete catastrophe. Their second? Somehow worse. Between high-stakes missions, chaotic undercover ops, and one very persistent rivalry, Black is certain of only one thing: Red is going to be the death of him. (And, much to his horror, he might actually care.)
