This is the book that got me into the romance genre and opened a whole new world for me. I also didn't realize how much of a sucker I am for the enemies-to-lovers trope -- and The Hating Game perfected it.
Lucy Hutton comes from a small independent book publisher. Josh comes from a big-boss corporate book publisher. Their publishing houses merge, and competition arises between the two. When a promotion opens up, they set their eyes on it, and will do anything to take each other down. However, once interacting outside of work, they realize they aren't so different as they thought they were. Their work lives may be different, but they are personally and intimately similar to one another. And our only job as the reader is to watch these two fall in love and grow for one another.
