The Fault in Our Stars by John Green
Diagnosed with Stage IV thyroid cancer at 12, Hazel was prepared to die until, at 14, a medical miracle shrunk the tumors in her lungs... for now.John Green's previous books are all great, and I've heard nothing but amazing things about this one. I'll have to read it next so I can see if I agree with all the hype (I'm sure I will).
Two years post-miracle, sixteen-year-old Hazel is post-everything else, too; post-high school, post-friends and post-normalcy. And even though she could live for a long time (whatever that means), Hazel lives tethered to an oxygen tank, the tumours tenuously kept at bay with a constant chemical assault.
Enter Augustus Waters. A match made at cancer kid support group, Augustus is gorgeous, in remission, and shockingly to her, interested in Hazel. Being with Augustus is both an unexpected destination and a long-needed journey, pushing Hazel to re-examine how sickness and health, life and death, will define her and the legacy that everyone leaves behind.
