Query: Entertaining But Not Fantastic

The book was entertaining, but not fantastic. The chapters alternated between psychoanalysis by a psuedo-sentient computer and then flashbacks to the actual story. Even during the story chapters, there was more focus on interpersonal relationships than on adventure. If that's what you are looking for then this book is absolutely for you. The characters were interesting and captivating, though not always well developed. For people who are looking for pure sci-fi adventure, this book isn't bad and definitely worth reading, but nothing exceptional.
