First, there is nothing new in this book. Everything he says here he has said in the earlier books. Second, there is very little in the way of plot or character development. You are halfway through the book before the threat to the universe is even described. All the characters are almost cameo reprives of previous performances. Except the new characters who are introduced and then promptly droped from the narrative. Third,the few more or less new notes are nearly all obvious reworkings from other writers. The eighteen month old hyperprecocious girl who knows the size of her father's erect penis and has started a waiting list of partners for when she begins having sex just reeks of the Lazarus Long style of deliberately shocking sexuality. Based on this book I would say Spider Robinson has become a tired old man.
