I tried to read the book. Made it about 50 pages before I DNF'd. The protagonist is just such a snobby condescending little shit. He whines about being ostracized and bullied but he constantly talks down to everyone at every opportunity. It felt like a power fantasy for the people who think other people don't like them because they're nerds, but really it's because they're just assholes.
They were girls that were super spies with awesome clothes, savvy smarts, and bond gadgets. For us teenage straights it was a fucking dream too 🤝
