Samuel “Sam” Bennett has no patience for Leo Callahan, the arrogant, sharp-tongued CEO standing between his hedge fund and a billion-dollar Wall Street deal. Every meeting becomes a battle, every conversation a challenge—and neither man is willing to back down. But after midnight, Sam has someone else. On an anonymous voice app, he knows him only as North. No photos. No real names. No jobs. Just late-night conversations, dangerous flirting, and a connection Sam never expected to need. What Sam doesn't know is that North is Leo. And when Leo discovers that the man confessing his secrets every night is the same rival fighting him across the conference table every day, he keeps the truth to himself. Soon Sam finds himself falling for two men at once: the anonymous stranger who knows him better than anyone, and the infuriating CEO he's supposed to hate. Except there were never two men. And when Sam finally discovers how long Leo has known the truth, their billion-dollar business war may become the least dangerous thing between them.
