As the proud owner of Guiding Star Enterprises, a wilderness tour company, he and his daughter lead a simple life. But when Kira comes crashing back into his world, he realizes God has other plans. Now, Lukas and Kira must confront a merciless killer as their past and present collide in a deadly race-a race they must win if they have any hope of a future together.
