Guardians of the Secret Portal

By Josiah Koh

When Astrid and Caius find a strange old box hidden in their attic, they don't expect it to change everything.

Inside is a glowing gem and a map that isn't quite what it seems, along with a secret their father has been keeping for years. One careless moment later, the siblings find themselves face to face with a real, living dinosaur, and a portal that won't stay shut.

What follows is an adventure neither of them could have imagined. A daring escape. A rescued egg. And a new addition to the family who turns their ordinary house upside down. But as the mysteries of the portal deepen, the siblings discover that some secrets were hidden for a reason, and that someone else has been searching for the same gem all along.

Guardians of the Secret Portal is a story about family, courage, and the kind of friendship that crosses worlds. Perfect for readers aged 8 to 12 who love adventure, mystery, and a little bit of magic in their backyard.
