The first book of a series can sometimes have trouble drawing me in and it didn't go quite as well as I had hoped. I liked the story fine enough, and also that the arc will follow the 3 books and only the relationship gets solved in each book.
I loved Lena a lot and Puck as well. Especially her(show spoiler)
I had a bit of trouble connecting to MC, because the POV was all over the place and not at any one person in length. Besides that it flowed rather nicely and I loved the scenes with the killer.
I think perhaps I need to read something else. Maybe a change of genre will be what I need.
