War is coming. The Galactic Federation and the ruthless Grovlic Empire are standing on the brink of conflict. As a new secret weapon threatens to shift the balance of power, legendary Striker Scout Joel Stinson is sent deep behind enemy lines to uncover the truth.

For his daughter Riley, every day is a lesson in survival. As a trainee in the elite mounted search-and-rescue division, she is facing the ultimate test—the brutal MOSAR Trial, where failure would mean the end of her life-long dream. Haunted by loss, rejected by her peers, and fighting to prove her worth, she must endure unforgiving terrain, treacherous obstacles, and the crushing weight of expectation—all while forces beyond her control threaten to shatter her family’s legacy.

As political schemes, high-stakes missions, and dangerous alliances collide, Riley and Joel are pushed to their limits. But are courage and loyalty enough to survive a battle against an enemy who has dominated the galaxy for a century?
