A fun, geeky sci fi adventure with some interesting theoretical science behind it. If you enjoyed books like Ready Player One, Year Zero, and Old Man's War, you'll probably love this one. Wealthy software magnate Bob signs up to have his brain cryofrozen on death in hopes of future resurrection -- but when he wakes up, he learns the US has dissolved and his brain is now property of a religeous state who has declared the deceased have no rights. Bob's intelligence has been uploaded to a self-replicating space probe with the mission to explore, multiply, and find colonizable worlds -- but he's not the only probe out there and the other countries are both trying to get theirs out first, and destroy Bob. The book follows Bob's mission and, without giving too much away, the plot takes several twists. My only complaint is that it got a little confusing switching back and forth between all the different copies of Bob, but overall it's well handled and all the Bobs are very entertaining. Not a book that left me with great life lessons or anything, but a fun read and I'll probably pick up the sequels at some point when I need some entertaining light reading.
