The Stone Warrior - M N Jolley - Bog

Her only ally is one she's paid for. Her only resource is the magic that makes her a pariah. What Adelyn has in abundance, though, is grit.
Raiders took her family for slaves, attacked her home town to steal what paltry wealth they had, and burned their crops for pure spite. Adelyn is resolved to take her loved ones back, no matter what it takes, but crossing the realm alone is no task for a teenage girl. Not even a teenage witch.
She needs help.
The bounty hunter she hires isn't her first choice, but she's not spoiled for choice and has no choice but to trust him. If that trust is misplaced, she doesn't have a backup plan.
If she doesn't come home with her family, she won't come home at all.
