Query: Not Good

I've read and enjoyed several books by John Ringo over the years but Von Neumann's War is one that I will discard from my bookshelf immediately.This book was nearly unreadable to me because of the mishmash of styles between Ringo's hard-boiled MIL-SF and co-author Travis M. Taylor's highly technical and verbose style. What resulted was a story that felt very stiff and academic even as it was trying to be a fast-paced thriller.Overall, this book focuses far too much on the science and not enough on the fiction as it goes on and on about technical minutia but leaves the reader wanting more in terms of character and plot.I've found that Ringo is at his best when writing alone or collaborating with David Weber. However, his mixed collaborations with other writers such as Travis M. Taylor, in this case, or Julie Cocherane in the case of Cally's War have turned out some of his worst material.
