This book has a lot of the trappings of science fiction-- life extending technology, genetically engineered pets, virtual reality games-- but the center, in the end, is the search for emotional completion engaged upon by Mia Ziemann, the protagonist of the book. In this book, Ziemann goes through a radical life extesion procedure that pushes her through the life of the young and vivid and out the other side through to the Holy Fire. Many things impressed me about this book, and I found it very hard to put down, but one of the things I liked the most was the truthfulness of the search for this elusive quality. Mia isn't instantly a great artist. She doesn't discover amazing abilities she should have exploited earlier. All she uncovers (but that 'all' is everything) is the will to carry through and develop for herself. There were frequent loose ends in the book (I felt like the memory palace and the Plato sequences were never developed fully enough) but the book itself was strong enough to carry them. Definitely recommended.
