Quick: You're on an elevator when the cable snaps, plunging you into free fall. What do you do? Jump in the air at the moment of impact, right? Sure, except that the elevator "will likely collapse...and crush you," note the authors of this fascinating sequel to the bestseller The Worst-Case Scenario Survival Handbook. The right answer: Lie flat on the floor to distribute the impact. In deadpan tone, Piven and Borgenicht advise how to survive a plane crash, remove a leech (burning it off will make it regurgitate, causing infection—who knew?) and escape from the trunk of a car. The scenarios owe a debt to action flick clichés—how often do you find yourself leaping from rooftop to rooftop?-but their utter implausibility doesn't make this read any less riveting.
