Rold Simms was a weather expert doing simple experiments on the planet of Caljunna. His sister, Vivian Tyler, dropped by for a visit. Immediately they were used to begin a war between Scientist and Industrialist factions. They escaped with the help of Blikki and Yosana, safari runners from a wilderness planet named Salkinia. Rold and Tyler were being used because their father was Malcolm Simms, highest on the Committee.
Ambassador Meacon and his daughter, Rachel, along with Ruth Poundstone (also on the Committee) were out to kill Rold and Tyler to convince Malcolm of the need for war. But the civil war of the Commonwealth could be affected by the information Rold harbors, if only he could deliver it.
Add Living Clouds to the Salkinia defense and huge Zeniam (ape-like) warriors to Poundstone's attacking force and you have the makings of the ultimate battle!
**** This one had excitement from the beginning! Lots of terrific strategies and fascinating cultures and a touch of romance that combine to make an excellent sci-fi story. I only wish more attention had been given to the Living Clouds! ****
