Yiayia is thrilled with the fantastically adorned Christmas sweater she made for her grandson’s dog, Ariadne. Her grandson Theo loves it too, but he can tell Ari does not feel the same way. Luckily, Theo knows exactly what will show her just how cozy and warm the sweater is—a hike to Echo Lake. And he can wear his new snowshoes!

The woods are a winter wonderland, and more snow swirls as they hike. But just when they reach the lake, Theo realizes Ari’s sweater has disappeared, along with their tracks and every familiar landmark. Could they have lost Yiayia’s gift and the way home?

Luckily, Ari spots something in the snow that turns out to be a surprising solution to their predicament. And when they get home, they find an even bigger surprise from that amazing Christmas sweater.

Drawing inspiration from Greek mythology, Jan Brett’s story of the bond between boy and dog radiates warmth and charm, while her signature border details hint at a final Christmas miracle sure to wow any crowd.
