This one was disappointing for me. I was tempted to skip based on some reviews here and I wanted to read it to see the partnership between Will and faith. However, it is brutal and needs a lottttt of content warnings, as per usual. It's not just the content that is intolerable but the characters also. 
I was not satisfied with the ending and feel like some things were not explained*. I think the only thing you miss if you skip this one is the introduction of Sarah, if you're interested in that. Otherwise, you can spare yourself some sanity and pass. 

*Unresolved points that are bugging me, beside just the constant wonder of how Will made it into the GBI - SPOILERS:

</Spoiler> - We're supposed to believe the parents of the perp just so happen to run over their son's victim? Their appearance, reason for being there was not questioned after they were discovered to be the perps parents WITH knowledge of what he does/has done to women.
- Anna is just gonna live without a rib now? There was not much more mention about this after she lives and miraculously recovers.
- Tom's wife... WTH. She was helping him, even if it was unwilling, she acted like a complete robot, but then at a certain point she begged for them to kill her husband. She said this multiple times, but it was never acknowledged, both in the moment and upon reflection of the case. </Spoiler>
