My book talks are coming at you from a librarian, not a reviewer. You won't find me talking about style or craft, why I think this could've been better or what worked or didn't work. I only do book talks on books I liked and want other people to know about. So if it's here I probably think it won't injure your brain if you read it.
The green bombs of World War III created air that was too heavy to breathe, air that crushes your lungs in a moment. Twelve year old Hope lives in a small community sheltered inside the crater from one of these bombs, protected from trespassers by a lingering ring of the compressed air released by the green bombs. The Bomb's Breath, as the townspeople call it, instantly kills anyone who wanders into it... but it's also the only thing that makes Hope feel special.
But Hope's inventions always fail, and her recklessness isn't appreciated by anyone. Until one day, bandits discover that the people of White Rock have figured out how to make antibiotics. Medicine is priceless, and when the town is invaded and held hostage, Hope is the only one who knows how to get through the Breath to go for help.
