The Time Travellers: Adventure Calling

A thrilling journey through time, bravery, and untold stories.

When cousins Saif, Aadam and Leyla stumble into a time portal hidden in a historic London building, they’re swept back to 1940s war-torn Britain and into a mission filled with secrets, spies, and real-life courage. Suddenly, history isn’t just something they read about. It’s something they must survive.

A powerful time-slip adventure that brings the past to life and shows the courage of ordinary people in extraordinary times.

Cousins Saif, Aadam, and Leyla are back — and this time, they’re travelling through history to witness a moment of true bravery. When the time portal sends them to 1857 India during the time of the British Empire, the trio must navigate danger, discovery and a growing sense of what it means to stand up for justice.

Along the way, they meet real historical figures, uncover hidden truths, and realise that history isn’t just about dates and facts, it’s about people who dared to speak out, resist, and dream of freedom.

Adventure Call is a gripping, heart-led story that blends time-travel with historical truth, making the past feel urgent and alive. Sufiya Ahmed’s writing is bold, thoughtful and full of feeling, shining a light on stories that deserve to be remembered.
