Gold Digger Platinum, Volume 1 — Fred Perry

Life for archaeologist/superscientist/adventurer Gina "Gold Digger" Diggers, her adopted were-cheetah sister Britanny, and their clone-fusion sister Brianna is rarely dull and almost always dangerous - and fun! Three years since saving Brit' from quasi-space, Gina has settled down (somewhat) as an archaeology professor at Georgia State, focusing her research on the Age of Wonders, some 7-8000 years ago. Despite her best precautions, she and her students face danger in T'uala, a mighty city buried two miles below the Baja Desert, and an adjacent fortress with a 130' siege crossbow! To learn more, they must visit the Library of Time in Shangri-La, where Gina gets a surprise reunion with one of her worst foes!
