To Anna, horses were more than a fascination, they were everything. Luckily, she had the opportunity to spend every summer on her grandmother's horse ranch in Colorado. Life was perfect, until she received the devastating news that her grandmother had been tragically killed. Anna knew she was the only member of her family who could take over the ranch and hopefully find new homes for her grandmother's beloved Arabians. Anna wasn't alone for long. Her grandmother had hired a local teenage boy to help tend the horses for the summer. Anna didn't stand a chance against Cody's quiet charm and the two rapidly become friends. However, even with the responsibilities of the ranch, Anna quickly discovers the secrets her grandmother had been hiding and a legacy that sends her on an adventure she never thought possible. An adventure in the saddle of a horse that wasn't a horse at all. Sabaska, her grandmother's favorite Arabian, was a Traveler; a magical being that could travel between worlds. With Anna at the reins, they find themselves trapped in a fight against evil with the highest of stakes… Their very survival.

Last summer, Anna's world got turned upside-down. It's hard to believe her travels to different worlds and fantastic yet dangerous adventures really took place. Little things, like the twinge of pain from her healing ribs, and a few relics, remind her that her journeys did actually occur. David, a ghost she met on her travels, suddenly reappears, bringing both old friends and foes back into her life. To help Sabaska, Anna must attempt to rescue captured Travelers from a Vanir stronghold, and still get home in time for school. An easy task compared to dealing with her mixed feelings for Cahir. Uncovering a Vanir plot to find a powerful lost mage will test her strength and dedication to the Travelers. With the help of new and old friends, they set out in search of the mage. He could tip the balance of the war in either side’s favor and it’s up to Sabaska and Anna to get there first.
