Sick was kind of a weird read for me. I went into it expecting this awesome, kick-ass crew of people fighting terrifying zombies that are in lockdown with them. But I didn't really get that, to tell you the truth. While there was zombies, and there was a group of people fighting them, most of the story centers around Brian and his problems with that. I felt like Chad (my personal favorite) would have been a better main character, because he was enlisting, and it seemed like he was doing a lot of the planning/fighting.
But since Brian was the main character, I'll talk about him. I didn't actually particularly care for him. He was so... indecisive. I felt like he didn't really know what he wanted, besides getting his sister safe. Which is a noble cause, yes. But once his sister was safe, it was his ex-girlfriend. It's like he didn't really care who got hurt trying to save "his" stuff. (Which it seems mean to call them stuff, but I'm just trying to make a generalization.)
I tried to like Brian, but... I enjoyed his friend Chad so much more! He was sweet, and even if he was prone to being a total jerk sometimes, it's still obvious that he cares. And I love what they start calling him towards the end... "Ten Ball". Like a billiards (#10 is blue stripe) ball, because of his mohawk. <3
Now, towards the end, all sorts of things started to get weird. I generally like zombie books (gross, rotting flesh eating monsters chasing people is so me), but... I felt like the zombies were kind of shallow-ish. Their part of the story wasn't as... filled out as I would have liked it to be. Not enough action or grotesque-ness, I guess. And to be honest, I never really understood where this "plague" came from. There was some kind of explanation, but I didn't really get it.
This could have been a lot more dramatic, in my mind. And the ending.. don't even get me started. I thought that the ending would be the clincher-- the thing that solved all of my problems with this book... but it wasn't. All in all, Sick just wasn't the read that I hoped it would be. Chad was the absolute best part... and I can't talk about him right now.
