The entire PREMISE of The Sun and the Star is built on the worst logic ever.
Hades sends his son to literal hell knowing that he could die just to get a Titan (who has his memories back, mind you) out of it. Because apparently 'Bob was getting too loud'.
If Hades can get that satyr out of Tartarus, then why the hell can't he get Bob out of Tartarus?
And don't tell me he can't, because Bob was literally allowed to be a janitor at Hades' palace when his memories were wiped. And Bob decided to be good, so Hades could easily take him out of there
This just says how bad The Sun and the Star is as a book.
I mean, why didn't Rick just give us short stories of Nico and Will between HOO and ToA? That would have been way better.
