Join our Twitter Book Club to discuss The Fault in Our Stars, a New York Times No. 1 bestseller by novelist and YouTube superstar John Green. This young adult-novel is told by 16-year-old Hazel Grace Lancaster, who meets a boy at her cancer support group, and ... well that would be telling! Reviewer Rachel Syme writes in NPR that "Green's novel is elegantly plotted, and as sad in places as one might expect a book about adolescent cancer to be. But it's also brimming with joy."

Together with his brother Hank, John is one of the two Vlogbrothers, who also host Crash Course, an educational YouTube channel. Their latest video is about the poetry of Emily Dickinson.
