Since Caitlin and Trevor vowed to assist the Otherworld and opened their enchanted antique shop, they've seen many strange things. But now, someone comes in asking for a mundane item: kitschy "witches" brooms. Has their magical life returned to normal?

As the couple prepares to host a family gathering, fate intervenes and something they've never seen before roars into their life: A creature out of Welsh legend and fantasy: A blundering, somewhat underdeveloped dragon—not at all the type of dragon they ever expected to meet. Forced to undertake his unique challenge, Caitlin and Trevor are perplexed by his demands, but the magical beast is certain they are the only witches who can help him.

Doing so might unlock an ancient hidden secret. Refusing might destroy them.
