Cady and the Bear Necklace

Cady, a 13-year-old girl of Native American heritage, has experienced major changes in the past year - her father's marriage to a younger woman, a new baby brother, and a move from Minnesota to Michigan where she attends a reservation school for the first time.  One school day, Cady finds an eagle feather on the floor outside a classroom and reports it to the principal.  When thanking her for this act of honor, he tells her that a mystery might soon appear in her life.  Later, Cady discovers an antique Indian beaded necklace hidden under the floor of her bedroom closet.  Is this the mystery the principal predicted might appear?  She consults with elders who tell her it is her "job" to find out why.  Helping her are her new friends Irish, John Ray and a talking blue jay.
