In Angel: Crown Prince Syndrome Angel Investigations is betrayed by one of their own. James, who had claimed to be an angel, attacks new member of the team, Laura Weathermill, when she calls him out on his lie. James injures her and Angel considerably. The incident is interwoven with a letter between James and his sister, offering to buy Earth. Turns out James is one of a powerful alien family.
Spike is having a soul problem. Conner is sought by multiple females, though none of them human. Later in the volume, Charles Gunn makes an appearance.
I am not quite sure of the chronology in the Buffyverse, but it is sometime after the end of the Angel television show. Everyone has a memory of hell, but also the belief that it did not happen.
There are lots of new characters with whom I am not familiar and the plot lines were a bit thin. I found this volume kind of meh.
