Catching Fire tells us what happens in Panem after Peeta and Katniss won the Games. We see Katniss falling in love with Peeta more and more, while she confuses her concern about Gale with love.
It's my firm believe that Katniss chooses Gale only because it's exactly the opposite to what the Capitolium wants. It's a way of rebelling against them. And I'm also sure she doesn't want to lose him, and she thinks she will lose him if she loves Peeta; so she still denies her love for Peeta.
IMHO, there's no real love triangle. Gale loves Katniss, but Katniss loves Peeta, though she doesn't know it yet. Deep inside, Gale knows he already lost her before having a chance to have her. Ever since she volunteered to go to the Game instead of her little sister, he lost her. He probably thought he would have her forever for himself, like Heathcliff in Wuthering Heights. The Capitolium took Katniss away from Gale and give her to Peeta, who had loved her since he was a little boy.
Now, I don't like Gale because he's a warrior, and I don't think he suits Katniss better than Peeta because of tht. I just happen to like him more, because, like her, he has suffered a lot and he keeps suffering. Katniss (Catnip) is his only chance to be happy. He really loves her, he wants to have children with her... And the poor guy ends up with nothing :(
Of course, I like Peeta. Like Gale says himself: "it's hard to hate him". He's really, really sweet, he would do anything for her. And he's the kind of character I love: a character who uses words instead of weapons to get what he wants. He can persuade anyone of anything. He's smart. I guess it makes perfect sense that he's the perfect match for Katniss. He can give her tranquility and peace, while Gale is kind of the same tortured soul as she is.
Gale undertands her. but Peeta can help her better. It's so obvious she's going to end up with Peeta...
This is my fandom mind working :D
However, the love triangle isn't the main theme here. The theme is rebellion. Katniss has become an icon of a rising rebellion against the Capitolium. The scenes described are so cruel and raw, so real... It hurts. And it's also really sad to see so much desperation and frustration against a cruel government.
Then, the Games. When you think they can't be more cruel, they prove you wrong. I was terrified as I was reading what was happening, the creatures and situations these people had to face... Terrible.
Oh, I couldn't believe that Katniss didn't know that Heavensbee was part of the resistance, because it was really obvious. Yes, she didn't know shit about any rebellion, but the guy showed her a... well, that bird, I forgot its name :)
I can't wait to read the last book, though I know how it ends because I've read spoilers (for the sake of my fandom heart)
Again, I strongly recommend this books (THG) to those of you who haven't read it yet. Read them!, you won't regret it :)
