A back and forth star meets spy story!

I almost gave this one 2 stars because of how back and forth the story is, the characters are. I ended up giving it 3 stars because the last 75 pages finally pulled me into the story when it revealed it's big twist. I saw part of it coming, but not all of it. And that's what made it end up pulling me in! The story ended up slowing down again, going back in it's game of back and forth. It seems the book ends in the back. We get a sneak peek of a forth in the upcoming sequel. I'm not too excited about it, because I'm not too sure I want to read anymore back and forth. If the sequel can maintain it's forth, I might be interested in reading it. I like 1/2 of the MCs, after all. Even if the other 1/2 got me angry throughout most of the book. The supporting characters and the antagonist are all likeable (or dislikable in the case of the antagonist). It is only the 1/2 that isn't likeable to me.
