Kealy Ryerson has everything a New York socialite could want: wealth, power, a devoted husband and loving children. Then her husband, a high-profile defense attorney, calls while she's at the salon.andnbsp; "Run," he says. "Take the children. Go now. Trust no one,"andnbsp; But Kealy waits too long--within a half hour, her husband is dead, shot down in the street, and now she cannot run: her apartment is under surveillance, and she can't get to her passport or any money. Her credit cards have been cancelled.andnbsp; She and her teenage kids are alone on the streets, with only their wits to keep them alive. But without her fancy clothes and expensive makeup, no one recognizes Kealy--not her husband's partner, not her best friends. andnbsp; Kealy is a poor woman of a certain age, who can walk invisible among the people who want her dead.
