The Passing Off as a Girl When You're a Robot

The book is structured around a series of topics in philosophy. Each chapter has a pretty deep philosophical problem at its heart. There's one interesting chapter towards the end when dotty gets injured, and they replace her with an alternative dotty. And for a short period of time, you've got these two dotties running around the world. Of course, it's a issue about personal identity and what counts as continuing over time.
