Run: Universe

The "RUN" Universe is a young-adult psychological thriller / survival-sci-fi / horror series by Gray Ellis (Grayabyss Media Group), centered on sudden invasions by mysterious creatures, government secrecy, and teases of parallel universes/multiverse concepts.

Core books

- "Run" (2020, ~38–40 pages): Follows Henry, a tough New York kid, as he fights to survive a night of creature attacks in his house. The story raises questions about the creatures’ origins and the lack of government warnings, with early hints at parallel universes. Tagline: “When all else fails, RUN.”

- "Run 2" (2020, ~38–40 pages; later Red Book edition also available): Focuses on Boston native Mindy Zeller (described as 9 or 13 depending on edition), a resourceful young survivor facing similar threats in her city. It expands the invasion narrative.

- "Run: First Legacy" (RUN: UNIVERSE Book 2 / expanded edition, published late 2025–early 2026, ~150–210 pages): Brings together heroes Mindy, Henry, and Justin. It heightens the survival action across a night of attacks while more explicitly teasing parallel-universe theories and government secrets as possible explanations for the chaos. This is positioned as a key installment that bridges the earlier short stories into a larger multiverse arc. The author has noted it deliberately sets up broader cosmic/interdimensional possibilities without fully resolving them.

Promotional material frames it as exploring a different kind of “hero” or nightmare figure in the same setting.
