Sons of Earth by James Cox

Twenty years after the Outlaw MC series, their children may not know the cost of war but they will know terror when Mars starts to reject humanity.

President of the Outlaw MC of Mars has a son—one that matches his temperament and the ability to find himself in trouble. Arie likes the notoriety a biker club offers, but being the oldest son of a founding member are big shoes to fill. When a quake makes the sleepy city on Mars rumble, Arie and his best friend Kavin are drinking in an off-limits spaceship. An unexpected kiss, followed by the quake, makes for one hell of a mistake. They take off without any ability to control the ship. Their destination? Earth.

There’s a lack of clothing, earth animals, and a growing relationship that leaves Arie confused about his future, but none of that compares to the dangers. Arie must now face a beast that nearly killed his father, and a love he never saw coming.
