Buggy Crenshaw and The Deadwood Principle: Evolution is the first of two volumes-Evolution and Revolution-and begins exactly where her last adventure Buggy Crenshaw and The Bungler's Paradox left off. While still reeling over her first encounter with Evil, 12-year-old Buggy Crenshaw is visited by the Rebel Phoenix Alabaster, an ancient and feeble creature whose cryptic message is only the beginning of one of her most harrowing adventures to date. With the help of her friends Sid Piccolo and Veronica Hamburg, Buggy deciphers the Phoenix's message to mean she must now face an even more sinister and alarming enemy: the Evil Empress Eartha Naturalus, the second of five Dark Lords of the Underworld. Although the Empress is presently trapped in her prison behind the Dimensional Door, this Wicked Mother Nature is still somehow causing world-shattering earthquakes and the startling arrival of black and twisted trees that rocket from the earth's core, destroying all that stand in their way. While the Empress' Legions begin their violent takeover of our world, Buggy and her friends scramble for a way to put a stop to the chaos before it's too late. Fueled by her unrivaled curiosity and admitted addiction to adventure, Buggy employs every bit of cleverness she has to save the world, but imagine her surprise when she learns that she was the scoundrel who caused this second coming of Evil.
