The thing with Marcus and Alex bonding occurred a little too quickly for me. They were cold to each other one second and bonding the next.
There are some horrible grammar errors. The story did have me thinking about who was behind Theo's murder and it becomes clearer as the book proceeds.
Alex struggling to get over his first handler and love of his life was a bit hard to read at times. I liked that the author could inspire such emotions in readers (well me anyway).
The double bonding and stuff was really interesting/exciting to read about.
