Portia

Alternate cover for this ISBN can be found here

Unlike her famous older brother Maxon, Princess Portia isn't known for killing demons or attracting admirers. The reason why is simple: a spell was cast on Portia, and the magic has marked her to one day transform into a dreaded Void demon. To fight this horrible fate, Portia’s spent her life hiding in libraries and learning magic. But when the Void demons threaten to destroy all the after-realms—and the handsome dragon Emperor Tempest offers his help—then Portia suspects that her future holds more than just a demonic metamorphosis. Fate is calling the bookworm princess onto the battlefield, and it’s a fight against both deadly enemies and her heart’s desires.
