'Through the Tree' follows a family with two teenage daughters who, when they were toddlers, discovered a doorway through an ancient tree. The doorway led them to the Land of Marqueria, where magic is real and unicorns exist. Now, as teenagers, they must lead their mother through the Tree so she can become who she was born to be. From Montana to Marqueria, the family is tested by danger and adversity. Still, they are bound by love, loyalty, and a determination to protect all they hold dear from the encroaching Darkness, which threatens to destroy the world.
