This book deserves not to have been read in 2025 when my brain is soup and I remember nothing about the previous books or basically any of the characters or what their losses were. 
Also I think I’m having a hard time with large scale saving the world epic fantasy these days. It feels more “flight of the deserter” than “escape of the prisoner”.  
Two comments behind spoilers - one thing I really liked that it did that felt new and one thing that felt very uninteresting-

I really liked the use of synesthesia to turn auditory magic into visual magic. That was cool. And I was…less than enthused by the ongoing use of “only the person who gave you your sperm can fulfill the prophecy” ad a plot point.
