In this newest installment of the bestselling Prehistoric North America series, animals and humans are struggling for survival amidst massive environmental change. Mammoths, mastodons, and giant lions have become extinct, and Rain Bear, the chief of Sandy Point Village, knows his struggling Raven People may be next. One day a beautiful red-haired woman, Evening Star, stumbles into his council lodge and begs him for sanctuary. He soon learns that she's an escaped slave from the North Wind People, a Caucasoid race and the Raven People's mortal enemies. If he offers to protect her, the North Wind People will attack, but if he sends her back, Rain Bear knows Evening Star will be tortured and perhaps killed.
