I don't even know how to rate this book.

The beginning of the book was crazy good, but then things changed.
First I must say, my favorite parts of the book were Seth's backstory, his "dreams". his "online" life
My least favorite part was the characterization of the other two main characters, Tomasz and Regine.
As much as Seth and even his friends from the other world felt real and fleshed out, these two felt unreal, to the point that I was waiting for a plot twist at the end.
They had the tragic backstory and everything, and their stories are VERY real, but I still could not connect to these two characters; frankly, I didn't care if they lived or died.
Tomasz was probably the worst one because he felt almost like a comic relief kind of character, but he wasn't even funny, he was just annoying to me. He was just weird, I expected him to be revealed to be a 40-year-old man stuck in the body of a child.

The plot-line itself though was interesting enough, but still, after a certain point, I was just waiting for the book to end.
