When Bronwen and Dylan are frightened by ghostly noises from the chimney on Christmas Eve, they run straight into the arms of their neighbour Mrs O'Riley. As they step next door for the first time, it's not just Bronwen and Dylan who can stop being afraid of what's on the other side of their walls – Mam might just find a blessing there too. 1930s Liverpool is brought alive with evocative drawings in a story that recognizes the richness of human kindness, even in times of hardship and poverty.
