One of the highlights of this series is the fact that the secondary characters are all strong personalities with their own viewpoints and agendas. So we’ve seen stories told by Stacia and Declan and now Caeco. Plus the short stories as well.
Having said that, I agree that returning to Chris’ POV would be a welcome change. Between fighting the Vorsook and agents of Hell and raising two kids with brand-new powers, there should be plenty of material for Chris to cover in the next novel.
