Iron Wars

Picoverse: a universe one million-millionth of our own, created by deliberately ripping apart the fabric of space-time.
A big-bang of an adventure, Robert Metzger's Picoverse boldly embraces the grand traditions of the genre, while exploding beyond the limits of knowledge, beyond the edges of the imagination, and beyond the boundaries of the universe as we know it.
Probably the most daring SF novel since Ringworld...mind-boggling. (F. Paul Wilson, author of All the Rage)
Bob Metzger knows his science. He proves it in Picoverse, a complex and intriguing story that ranges widely through time and space. (Charles Sheffield, author of The Spheres of Heaven)
Metzger has captured the essence of that good old time religion SF fans have worshiped since the genre began: a rousing hard SF tale with a true Sense of Wonder...This one is a winner. (David A. Truesdale, Editor, SFWA Bulletin)
A 21st century leap from the physics lab into the multiverse that only Gregory Benford, Philip José Farmer, and A.E. Van Vogt could have written-if they had ever collaborated. (Tom Easton, Reviewer, Analog)
