Kael’s Quest by T.J. Quinn

Kael left Zuvrak for planet Earth with a few of his friends to search for their soulmates. When they were about to reach the planet, they were thrown into a black hole that destroyed their vessel and forced to leave it in escape pods. Kael soon realized this planet wasn’t the Earth his mother had described to him.
People barely had any technology, and demons were hunting them, killing the men and stealing the women.Though at first Kael had no intention of intervening, he soon changed his mind, because the woman he was falling in love with was in danger.
