I hadn't read the 1st book when I read this one, you don't need to but probably would be helpful as there were a lot of call backs. I was able to deduce things but reading it first would've been easier. Matt & his twin CJ have powers I guess is the best way to say it. CJ can see the future and Matt can see the past, all with a single touch. CJ was the star for the first book so now its Matt's turn. Anna survives a serial killer and two years later is only just barely ready to date again. CJ sets them up. Now we have a copycat serial killer and they are following the original ones MO which scares the crap out of Anna. Things get a little wonky because Matt used his powers and misinterprets things. Good ole miscommunication trope. Its a quick murder mystery read with some good respectful spice thrown in.
