Update for second read-through: This time I had a copy with the prequel novella attached and that really helped with making sense of the world and technology. I was still really frustrated with how often Peri's mind got wiped so she had to re-figure-out everything, but I followed the overall arc of the plot much better this time 
 Original review is below 
 Peri Reed is a drafter--she can overwrite the last few seconds of her own life to fix mistakes or keep from being killed. But she loses chunks of her memory when she does so. Drafters have anchors to help keep them sane and remind them of what they lost, but when Peri's anchor turns out to be a traitor, Peri must try to figure out what's right and wrong, and who's side she's on. 
 I enjoyed this quite a bit; it's a lot different than the Hollows novels, but still a good read. It seemed to me that the technology and such wasn't explained as well as it could have been as early as it needed to be, so I was vaguely confused about some things until about halfway through the book. Also, the ending was really jumpy and kind of convoluted. But Harrison did a remarkable job grounding Peri to avoid making the reader really frustrated with her as she loses her memory over and over and has to try to muddle through her life without the memory of things the reader has "watched" her do or learn. 
 I hope Harrison can get the issues with her publisher sorted out, because I could see this being a really fascinating series.
