In the first novel in this series, Rhenn, the Imager, and title character has learned about his powers and has been indoctrinated into the Collegium, the group of Imagers who live on Imagisle in the land of Solidar. Modesitt spent a lot of time exploring philosophy, law, and the limits of power, to my mind too much time, but the character is interesting and the magic itself of imagining a new realty or new things is pretty neat magic.
In this second book, the stakes are higher for Rhenn. He has now been raised to a Master Imager and High Holder Ryel, one of the most powerful nobles in the land is seeking revenge against Rhenn because Rhenn caused the blinding of his oldest son. Ryel, uses his economic might and allies to attack, not only Rhenn, but also Rhenn's family, who are unknowing of the blood feud going on around them because the Collegium has told Rhenn that they cannot get involved in an individual's struggles with a High Holder. The Collegium apparently got involved once before in a power struggle and as a result many Imagers died, many High Holders died and the form of the nation was almost destroyed so there is an agreement that the Collegium will not act.
That leaves it for Rhenn to act on his own, but also secretly so that no connection can be made between his acts and those of the Collegium. And Modesitt telegraphs very early on in the story how Rhenn will accomplish his purpose.
Meanwhile, Rhenn's day job with the Civic Patrollers also presents problems. The Patrollers (which we would call the police) patrol the taudis areas, which are run by Gangs. Rhenn has befriended on of the Taudischief's Horazt, who's son is now a very young Imager. Rhenn, besides being a very powerful Imager also has flashes of foresight.
The middle of the book concerns how Rhenn uses his connections with Horazt and his foresight to aid the capture of a Taudischief, help the Tuadis with the Navy's conscription of taudis people with less bloodshed and thwart the plot of foreign agents.
This could have been interesting and exciting but basically it was humdrum and slightly boring. Modesitt starts chapters often with breakfast for Rhenn where he meets other Masters who either impart lessons on government or the use of power or fawn over his girlfriend. Modisett also has Rhenn paint pictures of two of the more powerful Imagers who also talk to Rhenn about the use of power. I do not think I have ever read a book where so much was made over what the character had for breakfast.
At times the novel reads more like a diary of the events in Rhenn's life. Modisett's point that Rhenn has to act and kill to save others is well played but the telling is long very long.
Good Character, Good Plot, Long Book
