For the young Mars colonies, it's a time when the latest technologies encounter ancient secrets, and mysterious forces threaten the rights of all free beings.

Kit owes a massive debt in repayment for a favor. To pay the debt, she and her singing partner Cary-who means more to her than she admits-must find a way to return ancient treasures to Mars from a distant system.

The task is technically impossible. But they have to succeed-in time to keep dark forces from grabbing enough power to carry out a very evil plan.

For Their Return is the fifth book in the Dreamers series.
