This is the sequel to Scholar. The first half of the book was pretty slow; the last third was much better. I would have enjoyed it better as an ebook I think; even though I was reading a hardback, the font was small, possibly smaller than a lot of paperbacks, and the width of the characters was thin so if you have eye problem it causes a lot of eye strain.
I like the first three books in the Imager series and all the Recluce (sp?) ones much better, but this was still worth reading once. I assume that the next book in this series will discuss the founding of the Imager collegium.
