I found this book to be terribly dull. I felt like I have seen it all before and this was neither a better version of it or added anything unique.
I did not like the switch in perspective. The heroine is in first person and then Jessi, one of her love interests, is in third. The other love interest is for some reason in love with the heroine though she used him three times for sex.
I didn't really get the heroine. If your so unique and there is only 6 nulls that are known of then why would you believe Dashiell would kill such a valuable asset as you are?
Just didn't work out for me.
