Magdalene Nox by Milena McKay

Magdalene Nox doesn't cast wishes upon stars... She simply makes them happen. But for this particular wish, she had waited for thirty years. Her retribution against those who discarded her three decades ago should be swift and simple.
Except a chance encounter and an unforgettable night turn her entire life upside down. Torn between vengeance and lust, Magdalene is forced to re-evaluate everything.
Can the Home of Dragons and lonely math teacher Sam Threadneedle—who finds herself stranded amidst longing and fury—withstand the storm that is Magdalene Nox, or will any and all be consumed by the flames of revenge?
Not everything is as it seems, and as Magdalene returns to the place that left her wounded and lost all those years ago, she realizes that old oak and stone hide more than secrets and pain. They also hold forgiveness and love.
