No one knows where the Tufa came from, or how they ended up in the Smoky Mountains of East Tennessee, yet when the first Europeans arrived, they were already there. Dark-haired, enigmatic, and suspicious of outsiders, the Tufa live quiet lives in the hills and valleys of Cloud County. While their origins may be lost to history, there are clues in their music, hints of their true nature buried in the songs they have passed down for generations. Private Bronwyn Hyatt returns from Iraq wounded in body and in spirit, only to face the very things that drove her away in the first place: her family, her obligations to the Tufa, and her dangerous ex-boyfriend. But more trouble lurks in the mountains and hollows of her childhood home. Cryptic omens warn of impending tragedy, and a restless "haint" lurks nearby, waiting to reveal Bronwyn's darkest secrets. Worst of all, Bronwyn has lost touch with the music that was once a vital part of her identity. With death stalking her family, Bronwyn will need to summon the strength to take her place among the true Tufa and once again fly on the night winds… The Hum and the Shiver is a Kirkus Reviews Best of 2011: Science Fiction & Fantasy title.
