Once Upon a Ren Faire by A. C. Castillo

When Keltia follows a handsome jouster, Emerson, into a hollow tree to hide, she finds herself in a fantasy land of giants, killer unicorns, powerful faeries, and dryads.

Keltia has a normal seventeen-year-old life. Except that she was found on the steps of a police station when she was a baby. And she was born with green hair. And no one knows why.

A fun day takes a fateful twist after a group of ren-faire barbarians who actually seem dangerous start chasing her across the grounds. When she follows a handsome jouster, Emerson, into a hollow tree to hide, she finds herself in a fantasy land of giants, killer unicorns, powerful faeries . . . and dryads.

Can Emerson help her find the key to return home? Or will Keltia be swallowed up by this impossible land?
