In The Fault in Our Stars, Hazel and Augustus met through a support group for cancer. They develop strong feelings for each other and eventually take a trip to Amsterdam to visit Peter Van Houten. While on that magical trip, Augustus tells Hazel that they found cancer in him again. Naturally, Hazel is very devastated and doesn't know what to do. After they've been home for a few weeks, Hazel receives a call and finds out that Augustus died. She doesn't know how to go on and frankly, is lost for words. All she could do was cry. After a while, she learns to live with the pain because she knows Augustus would want her to be strong for him.
