Thomas can’t imagine life without his little dragon Blink, who is not just a pet but a true friend. Growing dragons on the dragon-fruit tree in the garden with his friends Ted, Kat, and Kai is the most wonderful activity! But Thomas made a promise to his grandfather: they must let their dragons return to where they truly belong. Keeping this promise isn’t easy — not when they’re still having fun with Blink, Glow, Frost, and Sly. Not when they need to discover the dragons’ real home. And not when Thomas is so close to uncovering the secret of the mysterious dragon tree.
