2015 was a wild year for books! I remember hopping onto Goodreads every other week to check out what was trending, and boy, did some titles dominate the charts. 'The Girl on the Train' by Paula Hawkins was everywhere—psychological thrillers had this massive moment, and Hawkins' unreliable narrator hooked readers hard. Then there was 'Go Set a Watchman' by Harper Lee, which sparked endless debates because it was technically written before 'To Kill a Mockingbird' but published decades later. Talk about a literary time capsule!
And let's not forget 'Grey' by E.L. James, the 'Fifty Shades' series spinoff from Christian's perspective. Love it or hate it, it flew off shelves. Meanwhile, 'The Martian' by Andy Weir kept gaining traction after the movie adaptation hit theaters. Sci-fi fans couldn't resist Mark Watney's sarcastic survival tale. Oh, and 'All the Light We Cannot See' by Anthony Doerr? That Pulitzer winner had staying power, blending historical depth with gorgeous prose. It felt like everyone was either clutching a thriller or a tissue-worthy historical novel that year.
