Ugh, so great. I love these sorts of big concept novels, and this one combines serial killers with journalist with 20th century women's history with early 90s pop culture and it's just so good. It also uses time travel very well. When I saw a photo of the author posing in front of a Carrie-in-a-manic-moment-on-Homeland style corkboard covered with note cards and red string, I knew I was in good hands. She really knows what she's doing. So good. Go read it so we can talk about it!
