Taken (gravity falls and svtfoe crossover)

Marco was a mess. His best friend was gone and he was stuck working together with a perky two year old.

Mabel was determined. She was ready to get her brother back, no matter what it takes. Even if she had to work with a teenage safe kid.

Star and Dipper were gone. Taken by an unknown enemy.

I do not own Gravity Falls or SVTFOE!!!!!
