The 'Lunar Chronicles' series by Marissa Meyer is one of those YA sci-fi/fairy tale retellings that just sticks with you. It's got four main books forming the core arc: 'Cinder', 'Scarlet', 'Cress', and 'Winter'. Each reimagines a classic fairy tale protagonist—Cinderella, Red Riding Hood, Rapunzel, and Snow White—but with cyborgs, lunar colonies, and political intrigue thrown in. Meyer later expanded the universe with companion books like 'Fairest' (Queen Levana’s backstory) and 'Stars Above' (anthology of short stories), but if we’re talking pure mainline entries, it’s those four. I binge-read them all last summer, and the way Meyer weaves the characters’ arcs together by 'Winter' is downright satisfying.
Fun side note: There’s also graphic novel adaptations and a novella called 'The Little Android', but they’re more like bonus material. The heart of the series? Definitely the quartet. I still flip through 'Cress' sometimes for Thorne’s sarcastic one-liners—that book alone is worth the read.
