The Wild Way - A Tale of Two Times, #5

In A Tale of Two Times, experience the adventures-often bizarre, sometimes hilarious, and ultimately deadly serious-of two young women of the ancient Clan of Thiuderieks, who face a fateful cosmic challenge of which the world is unaware.  Their Clan possesses the world's only possible salvation, but its founder, Thiuderieks, has caused the challenge by his long-ago deal with the god Sunderer.  This has led to the Clan's eight-thousand years of skirmishes with Sunderer's Circle of evil humans and gods, but the time has come to settle accounts.
The young women, Rhoda and Yohanna, apply all of their considerable ability to stealth combat with Sunderer's Circle, aided by the men they love. Beginning in 1960s Texas, action soon shifts to Southern California, where Rhoda's hubris brings her to thoughtlessly kick-start the Clan's last War Thing with the Circle.  Rhoda shares her guilt and turmoil with her feisty girlhood friend, Yohanna, who becomes fully entwined in Rhoda's schemes.
The action culminates in a face-to-face confrontation between Rhoda and Sunderer, striking the War Thing's final, surprising blows, in the climax of this nine-volume saga.
