Allies Series

(6 reviews)

The Allies series by multi-award-winning author Tom Palmer is a wartime adventure series for middle grade readers aged 9+ who love a bit of historical fiction and learning about the world wars.

It's the 1940s and with a Nazi invasion looming over Britain, three unlikely friends – Bobble, Cadan and Cilla – must join forces to help their parents in vital but top-secret war work. The book opens readers to conversations about war, of course, together with friendship and found family, and it is fast-paced for all lovers of racing adventure.

We highly recommend this series amongst our other top choices of the Best Historical Fiction Series for 9 and 10 year olds, and to all fans of Armistice RunnerD-Day Dog and Over the Line.
