Some legends are real. Some secrets are worth protecting.

Sidney Lowell didn't plan to return to Silver Hollow, her sleepy hometown nestled against ancient forests in Humboldt County. But when her mother and grandmother vanish without a trace while investigating the mysterious creatures that have appeared to the women in her family for generations, Sidney has no choice but to come home.

Almost finished with veterinary school but lacking her diploma, Sidney takes over the family pet shop while searching for answers. The magical beings that only appear to the women in her family might hold the key to her mother's disappearance - if only she knew how to communicate with them.

Ben Sanders, a struggling cryptozoologist with a YouTube channel and a failed academic career, arrives in Silver Hollow chasing rumors of a glowing white horse in the woods. What he finds instead is Sidney - guarded, capable, and hiding secrets that could make his career...or destroy what's left of her family legacy.

When a logging company threatens the ancient forest that serves as a crossing between worlds, Sidney and Ben must race to protect the magical gateway. As they uncover Celtic symbols carved into trees and standing stones that appear only during the dark of the moon, the truth becomes clear: Sidney's missing family didn't just disappear - they crossed over.

With the unicorn as their guide and corporate greed threatening to destroy the portal forever, Sidney must decide who to trust with her family's centuries-old secret. Because saving the crossing might reunite her with her mother and grandmother...or seal them away in another world forever.
