Finished it last night. I can't wait to get my hands on the third book. I like the way these are written, because although the majority of the story is told from Conn's perspective, we get glimpses of the other characters when we get to read their letters and journals.
This book picks up where the 1st left off. Conn believes magic is a living being, but he is unable to talk to it because of the loss of his locus magicalicus. After Shadows begin attacking the people of Wellmet, Conn causes a series of explosions in which the magic communicates with him. He learns that the magic is worried. It wants him to go to Desh and figure out what or who is controlling these Shadows.
I think all readers at this age group would enjoy this series. Fans of magic and fantasy will find it particularly exciting.
