The Scientist’s Price by L. P. Peace
He will cross the galaxy to find her.
When Kadian agreed to help humans design an engine that could break the light barrier, he had no idea his heart would become the property of one human so completely. But she rejected him, even though he could see the fire in her eyes and feel the passion in her kisses. Then she left, on the same ship powered by the very engine they’d designed together.
When Olivia’s ship is attacked and the crew sold into slavery, Kadian will do anything, hurt anyone, stop at nothing to find her and when he does, he will allow nothing to separate them again.
His price for this rescue?
