That puts it among the most expensive book-to-movie deals ever, not adjusted for inflation, more impressive given the novel isn’t even available yet. First published in 2018-19 (no longer available online), SenLinYu’s Mancled can best be described as a cross between Harry Potter and The Handmaid's Tale.
