It was the best book with a sense of I ever read. I like the way John Green Create the plot , the characters was awesome. 
 I really like the part when Hazel played game with Issac. 
 *spoiler alert* 
 So we sat there for a couple hours talking to the screen together, navigating this invisible labyrinthine cave without a single lumen of light. The most entertaining part of the game by far was trying to get the computer to engage us in humorous conversation: 
 Me: "Touch the cave wall." 
 Computer: "You touch the cave wall. It is moist." 
 Isaac: "Lick the cave wall." 
 Computer: "I do not understand. Repeat?" 
 Me: "Hump the moist cave wall." 
 Computer: "You attempt to jump. You hit your head." 
 Isaac: "Not jump. HUMP ." 
 Computer: "I don't understand." 
 Isaac: "Dude, I've been alone in the dark in this cave for weeks and I need some relief. HUMP THE CAVE WALL." 
 Computer: "You attempt to go" 
 Me: "Thrust pelvis against the cave wall." 
 Computer: "I do not" 
 Isaac: "Make sweet love to the cave." 
 Computer: "I do not" 
 Me: " FINE. Follow left branch." 
 Computer: "You follow the left branch. The passage narrows." 
 Me: "Crawl." 
 Computer: "You crawl for one hundred yards. The passage narrows." Me: "Snake crawl." 
 Computer: "You snake crawl for thirty yards. A trickle of water runs down your body. You reach a mound of small rocks blocking the passageway." 
 Me: "Can I hump the cave now?" 
 Computer: "You cannot jump without standing." 
 Isaac: "I dislike living in a world without Augustus Waters." 
 Computer: "I don't understand" 
 Isaac: "Me neither. Pause."
