Hannah Dain, a skilled business lawyer, is on the verge of leaving her family’s law firm for a better job. But her plan is derailed when a real estate deal she’s put together suddenly goes bad. Two million dollars of investors’ money has disappeared. If the mistake was Hannah’s, her firm is on the hook for the whole amount.

Career on the line, Hannah decides to investigate—despite a disapproving father and antagonistic older sister. Having long ago abandoned efforts to heal the family rift, Hannah now enjoys her separate existence, whether drafting a complex IPO or bicycling miles through the hot Arizona desert. Although she exonerates the firm, a car bomb and two murders thwart the police's identification of the culprit behind the scheme.

At work on a new deal, Hannah is assisted by Cooper Smith, the firm's computer consultant and her former lover. Compelled to dig deep for key information, Hannah uncovers a greater threat all too close to home. Only by exposing long-buried family secrets can she save her reputation, her law firm—and her life.
