The Hechee will be forced to reappear after Wan is trying to find his father inside a Black Hole, in this book the reason of the Hechee hiding is given to us.
Robin Broadhead has his own fight with himself over the fact that having new tissues and organs is at the cost of other living persons, in this case money can't buy everything.
This book can be told as phylosophical more than adventures, but can be interesting for a scy-fi fan as me.
