Burning Stone (Tales of the Citadel Book 39)

Leyhara is a talent of Resicor and she took full advantage of her new freedom to hold off attackers by grounding their craft, by having the ground under them melt.

After the attack, she is given the choice to stay or leave and go somewhere she can use her power. It takes her minutes to make up her mind and she is on the next shuttle out.

Bohrvin has been waiting centuries for a woman who answers the call of his mind, and when he finds she has the ability to melt rock, he decides he had better tread carefully while courting a woman standing on burning stone.
