Mara's life is simple: work, friends, and quiet evenings at home. But lately, she's been feeling something. Her shadow is getting longer than it should. It tilts its head when she's not around. Sometimes... it smiles without her.

Then, one night, it disappears.

Mara wakes up to find herself in a strange parallel world, where shadows are flesh and blood, and the "real" Mara—her shadow self—has replaced her in her old life. Trapped in this unsettling world known as "The In-Between," Mara must uncover her true self before her memories fade into nothing more than empty fantasy.

But the more she searches for answers, the more she wonders: Was she ever real?
