We've all had that one book that feels like it has physically ripped our heart right out of our chest. A book so moving that we can't help but curl up and sob for a good hour after reading it. If there's a book that comes to mind, we wanna know!
Maybe it was The Great Alone by Kristen Hannah, which features a volatile husband who moves his family off the grid to Alaska where things fracture until they eventually fall apart.
Or maybe it was Aristotle and Dante Discover the Secrets of the Universe by Benjamin Alire Sáenz, which follows two boys exploring their identity and relationships.
So tell us: What book was so moving that it made you curl up and let out a cathartic cry — and why? Tell us in the comments below for a chance to be featured in a BuzzFeed Community post.
