Mostly academic politics (and some actual politics), slowly unraveling the mystery of an object with strange physical properties. Some action and romance is tossed in for good measure. Very dry and I'm not sure there's anyone I would actually recommend it to.

Glowing endorsement, right? Well, it was a VERY relaxing read for me and I enjoyed the science. Considering how idea dense I normally take my fiction, this single idea - extrapolated from a handful of "maybes" grounded in current (as of mid '80s) theoretical physics - managed to grab my interest and carry me along for the length of a novel. Mostly good writing. The "good" characters got fleshed out quite nicely - flaws and catastrophic mistakes and all - while the "bad" characters were cardboard cutouts.

Expanding my thoughts for a blog post.
