Flora and her packrat life are perfectly ordinary, perfectly predictable. She avoids strangers, especially opera-singing porcupines and rabbits that make prickly pear cactus pads talk. She's never flown through the air, nor drooped herself before a kangaroo rat king. And she would never talk with a blood-thirsty owl, because everyone knows owls can't talk. Besides, they eat packrats. Flora's perfect life is all about snuggling in her treasure-packed nest and 'snibbling' snacks with her packrat pal. There's only one thing--looming nearby is the dreaded cliff. Ever since she was a wee pup, other packrats have warned "beware " and Flora's stomach twists into knots. All this is about to change when old Grandma Mimi tells Flora about their ancestral home, stuffed in a dark crack in the cliff. Countless packrats have raised their young and left their marks and memories there. They stay away now, ever since a killer wiped out a litter of pups and took over. Flora tucks the story of the home deep in her heart...then tumbles into a faraway canyon. Can she survive dangers that seem to lurk around every tree stump? And how will she ever get home?
