When dad brought home a weird puppy from the foothills of the mountain one day, Tom and Denise knew she wasn't a normal dog. There was something very special about her. They named her Ylva.
Dr. Flock, the weird veterinarian, also seemed far too interested in her. The family suspected he knew more than he was letting on.
During a sleepover at the treehouse that weekend, the siblings and some friends embarked on a fantastical adventure to the Dylva Dynasty. There they learned that they were selected as 'The Chosen Ones' and were asked to help save the dynasty that was under imminent threat from bad elements in their own world.
Can they save the Dylva Dynasty?
