Ada and the Secret Garden

Emma, Noah, Alex, and Daisy love working with Ada, their clever classroom robot. Her blue eyes blink when she is thinking, and she can scan, calculate, and even play music — all at the same time.

Then one Saturday morning, Ada picks up a strange signal. It is coming from behind the school. The children follow her — past a broken bench, a rusty gate, and a sign that says Keep Out — and find a hidden door covered in thick vines. Behind it is a secret garden that nobody has visited for years.

But the gate has a number code. And the only way to open it is to solve a riddle carved into a stepping stone. Can the children crack the code — and discover who locked the garden in the first place?

In this A1+ reader for learners aged 9 and above, children enjoy an exciting mystery about curiosity, teamwork, and the environment, while building essential everyday vocabulary in English.
