An ancient prophecy foretells disaster, and only Penny, John and Ben Trevelyan can prevent it happening. They have survived the dark, magical trials of the Lyonesse Stone and the Seat of Storms. Now, their attempt to defend Cornwall from this looming threat leads them again on quests through other worlds and times. Can they succeed? – They are faced with the evil forces of the sinister Doctor Dee, the mystery of the man from the sea, and a much-feared face from the past. Ruthless pirates; the giant of St Michael Mount; mystic sea-caves; treasure from the Isles of Scilly; the ancient dolments of West Cornwall; the Sea Bucca; the monstrous Morgawr and the lowly Piskey; the lonely vale of a long-ago battlefield: all these and more encompass the fear, courage, adventure and sacrifice of The Tinners’ Way.
