Demon Bound(Crossroads Chronicles (Cannon)‪)‬

When a summoning goes awry, suddenly book nerd Meena's summer job becomes something drastically different. Instead of cleaning eccentric Carol's house, she's bound to a demon as his soul-collector. Soon Meena discovers that the boring, pageant-obsessed, bonfire-loving town that she's never fit in to is a hotbed for soul-sucking demons, demon-hunting witches, and vampires who just wanna have fun . . . And then she comes into her own powers.
Could things get any stranger? Good thing she meets new guy Jake-who gets her and still hangs around.
When Jake's mom sends him off to his Aunt Zelda's for the summer, he thought he'd be bored. But nothing is what it seems in this town. His aunt isn't just odd, she's a witch who fights demons and tries to maintain the magical balance of the town. Jake should get the hell out of there and, he would leave, except for bad-ass newbie witch Meena, who looks at him like he matters.
He never counted on sticking around, but Meena's bound to a demon who wants to destroy her soul-and Jake's finally found someone worth fighting for.
