*Note: These genre distinctions are debatable.
*Contenders for the spot Arcadia Awakens holds: Everneath by Brodi Ashton & The Shadow Society by Marie Rutkoski.
*If you need romance in your fantasy, substitute Throne of Glass by Sarah J. Maas for Witchlanders. (In terms of the "Character Driven" scale, I'd put ToG to the left of Shadow and Bone.)
*Note: I do not read a ton of horror, and YA doesn't have a whole lot of horror, so I'm not sure any of these are "strictly horror." In fact, most of these are or have elements of paranormal romance as well.
*In case anyone was tired of having a female protagonist*
*Also meant to put "Dystopia" for Under the Never Sky but forgot (since futuristic, y'know, isn't a genre and all :D).*
Authors who I very nearly put twice on the list: Maggie Stiefvater creates wonderfully unique male protagonists (Ballad: a Gathering of Faerie), and Gayle Forman writes wonderfully angst-ridden contemporary novels with higher truths embedded in their narratives (If I Stay).
PS - Look at those covers. Isn't it amazing how you can sense a pattern based on genre? (i.e. Sci-fi doesn't generally show faces, poetic dystopias do, etc. etc.)
