Mentored in Fire (DDVN #10) by K.F. Breene

After a life of hiding and laying low so as not to end up trapped in the Underwold, that's exactly where Reagan finds herself.

It could be worse, though. She could've had a hostile father as her jailor instead of a man eager to teach her magic. She might've been trapped with someone other than the steadfast Druid.

She could've gone her whole life without riding a dragon!

When push comes to shove, maybe the Underworld isn't so bad.

Or maybe Lucifer is doing what he does best - deceiving her to get what he wants.

Reagan must walk a razor thin edge to keep her independence.

She must battle wills with the lord of the Underworld.
