The sequel to Cluster. Once again, Anthony doesn't disappoint with lots of weird alien sex and bulging mammary glands. The main character, Melody of Mintaka, is a direct descendent of the two main characters from the previous book, only about a thousand years down the road. Once again, the galaxy of Andromeda has discovered a new way to try and siphon off the Milky Way galaxy's energy, which would result in, among other things, the destruction of said galaxy. Transfer technology has improved since the first book, so the amount of time Melody can stay in a transferee is greater than it used to be by something like a factor of ten, which is good, because she has to stick around for a while. By the end of the book, I became confused with all the transferring around, but as long as it made sense in the end, I'm sure somebody did their homework.
