Thanks to NetGalley for a copy in exchange for an honest review.

tl;dr
A dark, tense tale with a lot of action, interesting cast, and some fun literary references. Writing is sometimes hard to follow.

About
In an alternate Venice, the Dead stalk the streets at night. Mindless. Thirsty for blood. Only Ayanda has the strength to kill them, with a power that even she isn't fully sure how she got. But there are others like her, all with secret pasts of their own. And only together will they be able to overcome an evil even more calculating and sinister than the Dead.

What I Liked
I very much enjoy a literary reference that doesn't spend too much time congratulating itself. This book has several, including a handful of more subtle ones that fans of classic literature will find very satisfying. The lead characters all had unique powers and backstories, and the supporting cast are all very interesting. My runaway favorite character wound up being Andreas, who isn't even one of the POV characters. A lot of big fight scenes with a tense underlying mood that doesn't let up, and a genuinely threatening final villain. Anyone looking for something dark with a lot of action scenes will find them there.

What Wasn't For Me
The writing style didn't click with me. I had trouble differentiating between metaphor and literal in a lot of spaces. I think Yurei has synesthesia, but I'm not sure, because maybe the colors he sees are metaphors. Several points where someone's body turned "to stone" or their legs "turned to water" are probably metaphors, but given the context of powers in this world, I briefly assumed they might also be literal. The story is told from multiple first person POVs, and I sometimes struggled to identify which character's POV I was reading.
