Guardians of the World Gates (Book Two):
The Lost Sixth Gate

Two siblings. Hidden powers. A lost world waiting to be found.

Jay and Jill Warde are not like other eleven-year-olds. Jill avoids being touched and refuses to wear dresses. Jay struggles with loud noises and crowded places. Their mum calls it being on the spectrum. What no one else knows is that the twins are World Gate Guardians, chosen to protect ancient magical portals that open only at midsummer.

Strange fumes drift through the forest. Unknown alarm signals begin to appear – signals linked to no known World Gate. A red-cloaked figure watches from the shadows. And the Watcher returns, whispering of long-buried secrets and a Hidden World lost to time.
Guided only by their Guardian Talents and a small circle of animal allies – a black cat, a loyal sheepdog, and a sharp-eyed crow – Jay and Jill are drawn into a supernatural mystery that stretches back centuries. To find the Lost Sixth Gate, they must journey beyond everything they know and decide who they can trust… before the Gates open without them.

This children’s and teen fantasy novel is perfect for readers aged 9–16, but it also appeals to young adults who love portal fantasy, magical mysteries, and supernatural adventures. A strong fit for anyone looking for books with autistic characters in an adventurous fantasy series. With autistic twins at its heart, the story offers meaningful neurodiverse representation in a clear, fast-paced style that works brilliantly for reluctant readers, confident readers, and middle-grade fantasy fans alike.

Rich in magic, hidden worlds, family secrets, talking animals, and ancient folklore, this book will delight readers who enjoy adventurous series where ordinary children discover extraordinary roles.

The Gates are opening.
The twins are the key.
But can they trust the one leading them there?
