Go-Fast UFO

A middle-grade race through time

Plain answerGo-Fast UFO is a middle-grade adventure for roughly ages 9–13. A science-fair mishap, a secret janitor, and a shapeshifting starship named Whiskers send Ryan and his friends racing from the end of the Ice Age toward a hidden Martian beacon.

Five Earth minutes at every stop

The time-travel rule keeps the story moving: each jump opens a new place, problem, and piece of the larger threat while almost no time passes at home. The characters have to solve quickly, trust imperfect information, and keep Whiskers pointed in the right direction.

Real spark, fictional engine

The title nods to the real “Go Fast” military video. Later official and scientific analysis has discussed how geometry and parallax can make an object appear much faster than it is. The novel borrows the spark—something that looks impossible and proves more complicated—not the claim that the fictional story explains real footage.

Who the book is for

Readers who like quick adventure, humor, young teams, strange technology, time travel, and science-adjacent mysteries. Parents looking for a story that lets real uncertainty sit beside fiction may find a useful conversation starter.

Reader fitChoose Go-Fast UFO for the fiction route. It stands entirely outside the ADHD Hunter & Runner series and does not require reading any other Jeremy Criddle book.
