Zennor and Zephyrs

Emma Wilder’s magical shop in Penzance is finally thriving — until a team of marine archaeologists arrives to explore a centuries-old wreck off the Cornish coast, and their leader dies in a diving accident nobody can explain. Then the gifts start appearing: a barnacle-crusted gold coin, an ancient pearl. Offerings from the mermaids of Zennor, or warnings. As another body surfaces and the wreck slips toward an underwater trench, Emma realises someone is killing to keep its secrets buried — and the sea’s oldest magic is stirring in answer.
