Stone of the Sun — Shirley Raye Redmond

Finding out that she witnessed her own father's murder is a shock, but when April Cortes receives a letter from the grandmother she hasn't seen since she was five, she knows she must make peace with her past. The mysterious summons to her grandmother's sprawling Arizona ranch is irresistible.

Much to April's surprise and delight, Collie Cortes happily relates the family's ancestral history, including the legend of the Stone of the Sun, an ancient and valuable heirloom that was stolen at the time of April's father's death. Collie also confides that someone -- maybe someone on the ranch -- is trying to kill her. April hates to believe it's anyone she's growing close to, but she has already lost too much at this ranch and has no intention of letting anything end her new relationship with her grandmother.
