Escape one danger. Jump into another.... Twelve-year-old Hope has always felt a little different from everyone else who lives in White Rock. She tries hard, but she doesn't always think before she acts. She takes big risks. Sometimes her risks pay off, but sometimes...they fail. Sometimes she fails. Hope knows that the most dangerous thing about living in White Rock is that it's so close to the deadly Bomb's Breath - the invisible, 15-foot-thick band of air that's hovered over the Earth since the Green Bombs of the World War III. The citizens of White Rock live in fear of the Bomb's Breath. Only Hope has figured out a way to go through the it - and she's lived to tell the tale. But a massive quake rips across the Earth, the Bomb's Breath begins to lower over White Rock. It's up to Hope and her friends, Brock and Aaron, to make the dangerous journey far from home across the bandit-ridden Forbidden Flats to the the wilds of the Rocky Mountains to try to obtain the one thing that may be able to stop it - before the Bomb's Breath sinks too far and destroys them all. This time, Hope can't fail.
