I'm sad to say that I didn't like The Treatment as much as The Program. I thought the first half was a bit slow, since it was mostly just running away and trying to stay under the radar. But mostly, I didn't like how Sloane, James, and Realm all started fighting. I HATED Realm. I didn't like him in The Program and I hated him even more in The Treatment. I think he's a creepy, manipulative bastard, and I don't like him one bit. It pissed me off that Sloane didn't hate him.
So my biggest reason for not loving The Treatment was that forced, unnecessary love triangle. James was jealous of Sloane's friendship with Realm and Realm was spewing out shit like:
"I love you more than James ever could."
Just shut up already, Realm. You're a moron.
Then when James disappeared from the book all together for a while, I stopped reading for about two weeks. To be fair, a big reason was because this was over the Christmas/New Year holidays so I was quite busy, but still.. I'm shocked that I put the book down for that long.
When I finally picked it back up and James finally came back, I got into the book more. Things got exciting again, I loved him and Sloane together (they're seriously ADORABLE!), and overall the book was just a lot more interesting.
My only other gripe after that was the ending. It was extremely rushed. [spoiler]The entire book is all about "stopping the epidemic" and "taking down The Program". But the ending consists of: finally escaping The Program... then there's kind of a "a few weeks later" period and we read one short article about how The Program was shut down. It felt EXTREMELY anti-climactic. I was hoping for an epic take down, but we literally just get a short paragraph from a news report. I was just hoping for so much more...[/spoiler]
So overall I'd say I was a little disappointed in this book, especially after having loved The Program so much. But most people who are reading this one seem to love it, so I'd encourage you to give it a try if you loved the first book!
