She-Bear - Rove City, #7

Etele has a good life, living on a cold and snowy planet with a family and community who love her. But when sky fighters from Rove City show up suddenly and destroy her small village, her world is turned upside down. And when she discovers that her own father is the target of this attack, everything she once believed about her life is forever altered. Fleeing from the sky fighters and their now ruined town, Etele, her friend Natali, her two young charges, Maeve and Lazlo, and the surviving members of her village are forced to make a long, arduous journey on foot to the nearest city.
And when the first winter snow hits during their march, they are unprepared to handle its devastating wrath. Just when all hope is lost, a mysterious bear appears, guiding Etele and her companions to safety, and leading Etele down a path of discovery-about what happened to her village and why, her father and her family history, and most importantly, about Etele herself. This is the seventh book in the Rove City series, and a retelling of the Italian fairy tale, She-Bear.
