Compassion Be Damned by Rebecca Royce

It is the end of days…
Krystal has spent years locked in isolation, enduring torture day after day. It might drive a lesser woman mad. Her sudden freedom leads to a journey across the forbidding landscape. Unexpected allies appear, and new challenges block their path. Embracing every opportunity as a chance, Krystal must trust these five lost souls, her wild ability to heal, and most of all—herself.

They owe a debt they cannot pay…
Titus, Paden, Zeke, Ryland, and Jett spent years in bespelled servitude. Slaves to the unforgivable, they seek to atone for misdeeds beyond their power. Discovering a Sister alone in the woods, they pledge themselves to her service. Saving Krystal is more than a means to an end, though, as one by one she restores their hope, love, and faith. They will need all of their strength and hers. Loving her saved them, but losing her may save the world.
