Rosie's Place by Jonah Panicker

In a house where light itself is forbidden, Annabelle and her little sister Rosie have learned to live in perfect darkness.They navigate their home by touch and memory alone - soft pink walls, stuffed animals, dolls, and the faint scent of blood that never quite washes away. Annabelle protects her sister, whispering stories and drawing pictures together on their little whiteboard in the pitch black.But something is wrong with Rosie.She has been stealing the light. Every time a bulb flickers on, every time a flashlight beam cuts through the dark, Rosie drinks it in. The brighter the light, the wider she smiles. And with every stolen glow, another body appears - twisted, drained, and left smiling in the dark.Annabelle begins to find clues in the blackness: bloody handprints on dolls, a Floppy bunny soaked crimson on Rosie's bed, and terrifying drawings on the whiteboard showing two sisters taking pictures... one of them slowly disappearing.Now the darkness is no longer safe.Because Rosie is still hungry.
And she has started looking at Annabelle like she's the last remaining light.Welcome to Rosie's Place.
You'll never see her coming.A nightmare by Jonah Panicker.
