Rachel Peng, cyborg liaison to the Washington D.C. police, is trying to catch another killer, but this time the murders are personal. Two of her OACET siblings died on her watch, and Rachel can’t remember how. Fighting against grief and her fears that their deaths were her fault, Rachel has to catch a skilled arsonist who has visions of a master race with no space for anything he considers less than human . . . and she’s sure he’s not working alone.

K.B. Spangler lives in North Carolina with her husband and two completely awful dogs. They live in the decaying house of a dead poet. She is the author and artist of the webcomic, "A Girl and Her Fed," and author of novels and short stories. All projects include themes of privacy, politics, technology, civil liberties, the human experience, and how the lines between these blur like the dickens.

I am a huge Rachel Peng fan. I know she is part of an entire world based around a web comic, A Girl and her Fed, but I don't really enjoy the comic format (but I love the story) but the Rachel Peng series is written so that you don't have to be a fan of the series to read the books.

This one was a hard book to read but only because even though I had to spend a bit of time in the first chapters remembering relevent stuff from previous books, I then had to read a book with characters who I cared about dealing with grief and possible guilt and how you can't just go off on a murder spree because it could get more of your people killed.

I definately want to read the next book soon.

Pulls together the characters and themes Spangler has been building in the series, with new twists and turns. Complex and subtle issues. Good read!

I'm ready for the AppleTV series (if only!).
