This turns out to be the third in a trilogy, the two previous books being The Knife of Never Letting Go and The Ask and the Answer, neither of which I had read: it's a huge long young adult book about conflict between humans and indigenous inhabitants on a planet where telepathic projections ('Noise') are common but not universal, both among the locals and among their Earthling invaders. It's an unusual comment to make about a book, but the typography is startling - not just a different font for each viewpoint character, but also letters jumping around the page for dramatic effect. My copy came with a transparent dust jacket with more jumbled words on it. The writing is dense but also gripping - very tight first-person POV from the teenage couple who are the centre of the story, and from the alien forces acting upon them; the plot veers from conflict to deadly threat to negotiation to assassination, a real roller-coaster. I do wish I had started with the first book, especially if it's as good as this (and it won the Tiptree award so cannot be completely devoid of quality).
