Ripped Pages

Princess Valentina lives a reasonably comfortable life, but after her mother's death, her father gets tired of taking care of her and locks her in a tower. She spends years on her own, talking to the birds on her windowsill, and reading books with adventures she will never experience. Her plans of running away are usually left for another day because she knows the vast forest surrounding her tower is too dangerous to cross alone.
Until one day, another girl passes by on her horse and Valentina wonders if she’s finally brave enough to seize her chance of freedom.

Ripped Pages is a Rapunzel F/F retelling in the format of a novelette.
