Alex and Ruby are back in their FOURTH time-slip adventure, tumbling back into 1947! From multi-award-winning author Sally Nicholls comes another brilliant action-packed adventure for 7+ readers, beautifully illustrated by Rachael Dean.

When siblings Alex and Ruby tumble back through the mirror, they find themselves in the freezing-cold winter of 1947.

Food is scarce in the aftermath of the Second World War and life at Applecott House is hard.

As Alex and Ruby discover they must solve the mystery of a missing family heirloom to ever have hopes of returning home, their adventure takes them trekking across the snow and treacherous ice on a perilous treasure hunt.

Will they make it home and back to the present day or will they be stuck in 1947?

Full of action and humour and featuring exciting black-and-white illustrations throughout, this is another superb time-slip story which brilliantly brings history to life as part of an adventure.

'A clever vehicle for introducing the differences between then and now in an accessible way, with a fast-paced plot and a lovely spooky ending' - The Times on A Chase in Time
