Bel feels apprehensive about spending the lead-up to Christmas with her grandma at Lamont House, a sheltered housing complex converted from a grand Victorian home.

She follows its footprints through the snow and is transported into the past. Here, she discovers Charlotte, a Victorian girl her own age. Charlotte's little sister, Sara, is very ill. Charlotte has been searching for Sara's cat, Snow. She hopes the reunion with her pet might make Sara better. Bel is desperate to help find Snow, but the cat is nowhere to be found, and time is running out…
