Half a million years ago, a "Homo erectus" woman fights to save her tribe from destruction. "Mother of Asili," a novel by Debra Austin, continues the story of Snap, who was exiled from her birth tribe in "Daughter of Kura" and is now the matriarch of the Asili tribe. After a series of increasingly suspicious disasters, she must discover whether the threat to her people comes from a reserved stranger, from Kura, or from within.
