Books That Make Readers Clash

"SECRET KEEPER had one of the most satisfying endings I've read in a long time," said one reviewer.

Meanwhile, on Goodreads, another reader disagreed: "I didn't really like the ending, but I loved the rest of it."

Of all my books, SECRET KEEPER seems to be evoking the widest range of gut responses.

Is there a particular book you've loved that another reader wanted to fling across the room? Or vice a versa, maybe: you wish you'd never read it because it left you sad, mad, or otherwise disturbed, but other people apparently adored it?
