This book provides a fun romp through a future post-singularity universe, where the singularity itself included the creation of a sentient artificial intelligence called the Eschaton. The technology in this book is fascinating (cornucopiae machines, FTL communication via entangled bits, ship drives) although perhaps not fully fleshed out—but technology was not the point of the book. It feels more like an author’s lark, containing subtle (or not so) pokes at bits from our own history (the jabs at “Jusef Smith” did make me chuckle). The characterization is exceedingly thin, the romance is (as too often happens) pasted on top of the plot, but if you can set that aside and skip to the fun tech bits, it’s an enjoyable read.
