One of the Japanese promos calls it "Da Vinci Code meets Jurassic Park".I think that sums it up pretty nicely. It's got dinosaurs, spies, intrigue, action, and conspiracy, all rendered in lovely film noir-esque art with a little fan service cherry on top (Lily!).And for the slightly geeky, it's got cool (and sometimes obscure) references to art, literature, film, history, science... you name it. Definitely a manga for adults!
