My husband thinks I'm mental

UPDATE.........I GOT ANOTHER ONE! My bribe of my younger brother finally worked, and he just started reading it!!! ........

I honestly don't know how to explain my obsession to him. It's like since I've read it I've been acting like I've joined some weird cult and I'm desperately trying to recruit more members(I'm terrible at actually getting people to read it, I've only managed to convince my sister so far, I'd definitely be punished for something for how awful I am at recruiting others if this was an actual cult) . I've now bribed my younger brother to try to convince him, but the little bastard is trying to renege on our deal. My husband doesn't understand why I care so much, and considering I turned him off ever reading this series, I doubt I can ever fully explain.
