"Jonna and Rainbow are sisters, but that doesn't mean they're all that similar: Rainbow's the bookish one, Jonna is the whirlwind. Jonna's also incredibly strong and nearly invulnerable--which will come in handy as they search the ruined, monster-infested wasteland that was once their home while looking for their missing father. Their world, once lush and bountiful, has been overrun by giant monsters and prickly, unnatural vines that strangle the life from the natural flora and fauna. Their differences sometimes feel bigger than they know how to handle, but the girls set out across the broken land to reunite their family, following other survivors and word of mouth from one place to the next. From a cave of huddled refugees to a hidden city of humans that have built a home in the shattered remnants of a mighty redwood forest, things are rarely what they seem. One thing is for certain, it's a thrill ride from start to finish, and Rainbow and Jonna won't stop till they find their father... and maybe even save the world!" -- Provided by publisher.
