In Don Winslow's The Dawn Patrol, Winslow writes the final showdown between Boone and the bad guy as an old-fashioned fistfight, like it's a 70's movie, but intercut with that, Sunny Day is riding the big swell for a chance for surf sponsors to notice her skills on a board and make her hobby into a career. Both are great, but it's a testament to his skill that the surfing is just as tense as the big fight. Doing two different scenes at the same time and making both equally nail-biting is quite the feat and Winslow pulls it off in spades.
At the end of Winslow's The Winter of Frankie Machine, Frankie is facing the bad guys, hugs his daughter and whispers "Don't worry baby, they can't kill me. I'm Frankie The Machine." I've read the book twice and got chills every time. I can't wait for it to be a movie, it'll be instantly iconic if De Niro or Jeff Bridges or some other great actor getting up there in years says that line.
And, of course, the ending of Savages. Don't anyone spoil it, but if you read the book, you know it's great. Tragic but beautiful, the only way the story could end. (Really, fuck Oliver Stone for ruining that.)
In the middle of John Connolly's The Killing Kind, protagonist Charlie Parker, while sitting in the kitchen with his girlfriend, decides he doesn't want to drink anymore and finally admits to himself that the murder of his family wasn't his fault and he would have died too if he had been there.
Lamb by Christopher Moore: Jesus is on the cross. I had been a Christian for a couple years when I read the book and while Jesus getting killed was a bad thing and got a bum deal to me, it never really hit me until I read that book and saw it through the eyes of Jesus's best friend who tries everything to save him. I was actually sobbing the first time I read it. I'm not much of a Christian anymore, but admire Jesus's teachings about just being decent to your fellow man and Lamb made Him human to me.
C'mon guys, play the game with me and Dave. It's fun. And it's convinced me to finally get off my ass and read Dog Soldiers. David Corbett loves that book too.
