Although John Green is already a best-selling and award-winning author with two collaborative works and four books, The Fault In Our Stars is easily his most ambitious work. Not only does he take on the challenge of making his ill protagonist an adolescent girl, he also molds together a near-adventure story into a beautifully moving contemporary classic.

The Fault In Our Stars is a breakthrough in simultaneously taking on the awkwardness of adolescence and challenges of living with a terminal disease. Although he takes the subject matter head on, his decision to make Hazel sick from page one immediately casts the affliction as expected and accepted because it has to be. This makes it possible to laugh with the characters throughout, even when the story takes a crushing turn toward the end.
