Catching Fire - Suzanne  Collins "When you're in the arena...you just remember who the enemy is"
Katniss Everdeen has survived the 74th Hunger Games, but that doesn't mean life is a walk in the park. The 75th Hunger Games mark the Quarter Quell, a special anniversary of the Hunger Games, and Katniss, as a victor, is expected to make her rounds to the Districts to promote the games. That means continuing her charade of being madly in love with Peeta, avoiding causing any more sparks of rebellion, and trying to keep on President Snow's good side. But things don't go as they seem as the 75th Hunger Games approaches

I Liked:
This book is fantastic! It isn't very often I read a sequel that is just as good or better than the original, but mark Catching Fire as one of the few that does!
Our characters return in all their glory. Katniss continues to seek out protection for her mother, her sister, Gale, and Peeta, thinking little of her own self in the process. She continues to be an intelligent, capable protagonist while also not becoming an omniscient Messiah figure in the process. Heck, most of the time, she tries NOT to a lead rebellion! Peeta continues to charm as the poor, "rejected" boy, having to use his words to cleverly make up for Katniss' brusque personality. Haymitch is back, guiding our victors through their trials, all the while barely staying sober It's so good and refreshing to read a sequel in which our favorite characters don't drastically change into some facsimile of what they were.
But what I found most impressive was how Catching Fire refused to repeat the same storyline as The Hunger Games. I've noticed in series (specifically for children or young adults) that this is the case. Not here. There is a Hunger Games that occurs, but it in no way is similar to the one in The Hunger Games. We have the starts of rebellion, Katniss must try to quell the rebellion to save those she loves, and absolutely no Romantic Triangle from hell (despite many claims to the contrary, there really is no Team Peeta/Team Gale). I'd love to detail more of what made this novel special, but I am afraid I would be leaving behind massive spoilers, and that would just ruin the surprise in the novel. And since this is a novel you should read, I wouldn't do that at all.
Closely tied in to above is how the book kept me guessing. Just when I thought I knew where the book was going ("Oh, it's going to be a rebellion novel", "Oh, it's going to be a travel novel"), Collins took the book in a completely different direction. And that direction was both good and surprising and MADE SENSE.

I Didn't Like:
If there was one thing I didn't like, it was how dense Katniss was. There were numerous incidents displaying rebellion or some other plot point (that I can't tell you because of spoilers!) that were obvious to me, and I am certainly not the most astute reader in the universe. And yet, Katniss was completely oblivious. Does it keep with her character? Yes, but here, it is somewhat more annoying and definitely on a larger scale.
Also, it does take quite a bit of time for the real "action" to get going. The first part is more than a little bit slow and plodding as it sets up the last portion and even the third book.

Dialogue/Sexual Situations/Violence:
Mild (PG).
Katniss and Peeta share a bed (rather chastely) on a few occasions. Finnick is said to be quite the Ladies' Man. Johanna walks around in the buff at one point.
Heavy. The whole point of the Hunger Games is to kill all 23 other candidates. Some of the deaths are off-screen, but others are pretty detailed and bloody.

Overall:
What are you doing reading this review? Go out, find this book however you can, and read it already! If you loved The Hunger Games, you won't regret it.
