The series

At a glance.

The complete standalone middle-grade novels of Ross Welford, gathered as a single body of work rather than a numbered series. It runs from his debut, Time Travelling with a Hamster — a boy using his late father's time machine to undo the accident that killed him — through What Not to Do If You Turn Invisible, The 1,000-year-old Boy, The Dog Who Saved the World, The Kid Who Came from Space and When We Got Lost in Dreamland, to the parallel-world quest of Into the Sideways World, the rewilded 2425 of The Monkey Who Fell From The Future and the time-machine rescue of Time Travelling with a Tortoise. Every book is self-contained and shares Welford's trademarks: a huge scientific premise, cliffhanger pacing, ordinary and funny young narrators, and a genuine emotional undertow. Read any one on its own, in any order.

Reading order

These are standalone novels and can be read in any order. The one soft link: Time Travelling with a Tortoise is a standalone-friendly sequel to his debut, Time Travelling with a Hamster — reading the Hamster first adds depth but is not required.

    Ross Welford's standalone novels

    Nine standalone high-concept Welford sci-fi novels; read in any order.

    Nine self-contained Ross Welford adventures, unified by voice and approach rather than plot. Each takes a single audacious idea — time travel, invisibility, immortality, a dog-killing virus, an alien abduction, shared dreams, a parallel world, a rewilded future — and drives it through a ticking-clock plot narrated by an ordinary, funny kid in over their head. From the debut Time Travelling with a Hamster to its late sequel Time Travelling with a Tortoise, all nine pair a huge sci-fi premise with a genuine emotional core, and can be read in any order.
