Time School: We Will Honour Them

Nadia Kaminksi knows very little about her Polish grandfather and her Polish roots, so how is she going to write a speech about him to read at his funeral?
Along with fellow time-travellers, Jess, Tomma and Ash, they find themselves on a train journey to the past.
Who is Marcel? And why does he have the same name as Nadia? Is this a chance for Nadia to find out who she really is?
It’s time to board the train for another adventure back in time.
