**Elanus** by *Ursula Poznanski* is an alright YA thriller/mystery. (Keep in mind that I'm not the intended audience anymore, though). She writes a very good unreliable/unsympathetic protagonist – a way too smart 17-year old boy, who by way of his self-built illicit drone stumbles into a dangerous secret at his new school. Very solid writing. It's very clear from the start that the protagonist is kind of an asshole, but I guess with YA you'd want to make this clear, to encourage engagement with the book (and to prevent any kids from finding him too much of a role model). Well-researched in terms of technical capacity, well-written, and while the twist is a bit predictable, the book is still pretty solid.
