If Dark-aligned Mia Evers had a choice between facing the start of high school or dealing with power-hungry demons, she would totally take the demons.That is, until one of those demons decides to call in the favor Mia owes her (it's a long story and totally not her fault...mostly). The demon Tradereth sends Mia on an extracurricular quest to find a deadly (naturally) relic that probably means really bad news for everyone.It's not like Mia has time to deal with these shenanigans. Things aren't bad at home, but that's because there is no home with Dad still in prison, Mom in the hospital, and her and Bela in separate foster homes. Stuff is getting weird and awkward with her friends (they call it growing up, but whatever). And joining the youth group of the Grand Light Order probably wasn't the best life choice she has ever made.But, speaking of bad life choices, the demon's quest might just be the worst one ever because, after everything Mia did to get Tradereth to leave her friends and family alone, it turns out she may be the deadliest threat to them all.
