Dr. Leigh Stathos likes her ER shifts fast, furious, and adrenaline-infused—"Treat 'em and street 'em"—with no emotional complications. Life's taught her a soul-rending lesson: nothing lasts forever, including marriage. And the clock is ticking toward the end of hers. Then an unwelcome confrontation with "the other woman" begins a whole new set of lessons.

San Francisco police officer Nick Stathos never gives up, whether protecting his patrol neighborhood, holding fast to faith—or trying to save his marriage. Seven days is all he has to reach Leigh's heart. But when a desperate act of violence slams Golden Gate Mercy Hospital into lockdown, it starts a chain of events that will change lives forever.
