I found this first book of the second trilogy more engaging than the first book of Violet's story, which is saying something. The mystery is interesting, Calla has her secrets, the mysterious vigilante tattoo artist, that we later learn to be called Chase, has his secrets and it all leads up to a very interesting plot and a very, very very shocking revelation at the end that kept me up half an hour after reading the final chapters in bed. I wish I knew how to write a sentence that makes sense without spoiling things. All I can say is I was not expecting that!
