Brittany Scott is coasting through the life her parents always wanted for her: a college degree, vet tech school, and now, a great job at a veterinary clinic in her hometown. When a new doctor joins the team, however, Brit realizes how insecurity has kept her in a stagnant existence: she never takes on any challenges, and always keeps people at arm's length. Brit decides it's time for a change, starting with her superficial relationships. After recruiting her favorite work acquaintances, she embarks on a road trip of self-discovery. While exploring in Boulder, Colorado, Brit and her friends are approached by a mysterious stranger. Speaking in ancient riddles, he discloses the directions to an Arapahoe legend, the Cleansing Pool, located deep within the Rocky Mountains. With the help of Brit's friends-and two men they meet along the way-the group discovers that the pool is actually a portal that pulls Travelers through the universe. With the discovery of her rare destiny, the universe is at Brit's fingertips, and she holds one of the master keys to pass through any door. She must now save our world from a tyrant plotting to avenge his father's death. It's a race to the finish line, and human existence is at stake.
