Crimson Bound, by Rosamund HodgeRead about another entry on the list.
Rachelle has very good reason to fear the forest: as a teenager she strayed from the path and was marked by a Forestborn, making her an agent of darkness. Though she devotes her life to protecting her kingdom from forest creatures intent on killing mankind, Rachelle knows it’s only a matter of time before the Devourer returns and the forest overtakes them. With the help of the King’s maimed illegitimate son, Rachelle must face the forest (and her own darkness) once and for all, and attempt to slay the creature that awaits her.
