The beginning was good but then it meandered in the middle before picking back up in the end.
Spoilers follow:
The save point use should not have allowed Jason to keep any items or experience, only his memories. This would have drastically changed how they cracked the vault. Also anything from an alternate timeline no matter if it’s destroyed in the primary timeline or not should also not be allowed, not at relic level, without calling the hall monitors. Katie’s power is beyond OP, especially with contracting power and agents. Her time would be infinite and it seems to have no limits.
Plot issues aside I enjoyed getting back to a Jason centric book with hijinks from the Fin and Co. outside the game. The epilogue was a curve from left field. I’m not really sure where the plot is going with it. The many sermons about lying to yourself also got old fast.
I had thought the main series was done with Armageddon but apparently not. Guess we will see where it goes.
