Stuff I've read lately

"Manifold: Space" (Stephen Baxter) - This is a continuation of the Manifold: Time "manifold universe". It is basically an alternate history (near future), where now there are many alien intelligences (thanks to our hero's efforts in the first book). Baxter attempts to deal with the Fermi paradox by claiming galactic catastrophes. I'm not familiar with the physics involved, but it wasn't real satisfying. I liked the first book better, but this one had some touching points, and some interesting tech.
