It's not a bad story, but it's glacial, more and more of the same-old same-old. Self-loathing on Roan's part, and poor-poor-poor Dyl on the other. And The Church is... well The Church. After Eli died it's more of a crutch than anything else to carry the story on.
The cat-fighting episode resembled the snuff case too much. Stray cat cases are really more of the same as well.
The story on the whole doesn't really progress a lot over 600+ pages (on my iPad). The only momentum there is comes from Holden. I don't deny - Roan changes, but only physically so. To himself he is still a monster. To everybody else AND the readers poor Dyl is still poor. Andrea is too eager to convince us that Dyl is happy, but I don't see it. He is not. He is upset and crying and too worried.
To me, what I see right now looking back at book 7, is a freeze. There is something going on under the surface (and the title is perfect in that sense) but the surface itself is frozen solid. Nothing changes except for that weak undertow under the solid thickness of ice.
2.75 stars is all I can give it.
