The sequel to Infinity Gate. This seemed to have more techy info dumps and I had trouble with some of the science, but that didn't hurt my enjoyment of this fast-moving story of AI versus organics across the infinite Earths of the multiverse. The war between the Pandominion (sentient organics, including humans) and the Ansurrection (AIs) has ratcheted up and the Pandominion has a plan to destroy the machines. Rupshe, a powerful AI on a non-affiliated Earth that suffered a decimating war a decade ago has its own plan, along with a small team of organics and AIs to help.
Aside from my poor job of summarizing the plot, this is a immensely readable book, with memorable characters, especially Paz, a teenaged girl from Ut, a version of Earth where the main sentient species evolved from rabbits instead of apes. Paz, with her digital implants (including part of her brain as part of a life-saving surgery), becomes the key to ending the war. This is a story with a lot of heart.
