A solid read, and I really liked the author's prose and characterization of the main character. It also explored some big ideas of the future of the universe, what it means to be human, the morality of warfare, and obligation to one's creations. Sadly, it felt a little disjointed, which is to expected from an expanded short story. Some of these sections could have been their own book, which would have made a great base for a series. The plight of the engineered being who is mentally broken and actually trying to kill herself, only to be stopped by the rubber-room society she finds herself in. Some of the alien planets explored from ideas in fighting the Shiva, the Shiva themselves, an alien species that just ceases contact with everywhere it invades, the galaxy after mutually assured destruction with automated defenses still active, etc. Some of these ideas reminded me of the Bobiverse.
One thing I found quite surprising is that it was written in the 90s, which felt off with how it treats women. Feels almost like an a Heinlein book. The driving force for the main character was finding his wife after she's frozen to stop an incurable disease. Touching, except freezing and potential future resurrection was never discussed with her. It's portrayed as a moral quandary, but it's on the basis of derailing the main character's life and not on informed consent. Throughout the book, women throw themselves at our main character. There's also the very troubling element where the main character, who is either wrapping up his undergrad or is in a graduate program, falling for the girl he marries. She's described as looking about 15.
