Definitely enjoyed seeing Tom struggle a bit with the possibility of being Orcus rather than just misunderstood. A couple of things that stuck out:
1) At some point Tom’s anxiety over possibly being too paranoid starts to be repetitive if there is not some kind of resolution. I like that him being a teenager is finally addressed, but by the third or fourth shift to Tom’s perspective I was looking for some other plot movement. Seeing his own portrait was a fun additional payoff that ratcheted up the tension, but at some point it seems that Tom is just spinning his wheels.
2) In the latter two volumes Tom seemed to get the opportunity to kick more ass, I definitely missed that. Using fire magic to sink ships, some hand to hand combat with knights rampant, I kept waiting for a bit of mayhem to break up Tom’s anxiety attacks in Apostles but became convinced it was going to be all bunched up at the end. Not sure if you can parachute some more demonic violence somewhere in the middle of the book (aside from flammable d’warg farts–loved that), but if so that would definitely fun to read and break up Tom’s primarily internal struggles.
Anyhow, this was tons of fun to read!
