And so it begins. Susan Cooper's The Dark Is Rising Sequence evolved a lot over five novels and twelve years, but Over Sea, Under Stone grounds the story firmly in Arthurian mysticism, which has inspired Western lore for untold centuries. Simon, Jane, and Barney Drew are visiting the village of Trewissick on the coast of Cornwall, England with their parents as our story opens. They're staying at Grey House, a manor being rented by their great-uncle Merry, also known as Professor Lyons. He's a peculiar fellow, an old, old man of indefinite origins; he's not a blood relative of the Drews, but has been a close friend of the family since long before the children were born, and they admire him as a man of deep, searching intellect. For Simon, Jane, and Barney, the Grey House is an invitation to adventure; long, musty hallways and side passages lead to hidden doors and massive attic spaces, where any sort of long-lost secret may be kept. The house is owned by a Captain Toms, but "Gumerry"—as the kids sometimes call Great-Uncle Merry—is in charge, and doesn't mind if the Drew kids explore. What intrigue might the manor hold for them?
It isn't savvy so much as luck that leads Barney to stumble across a tattered map in a forgotten corner of the attic. The paper looks hundreds of years old, and the faint handwriting is hard to decipher, but that's what Great-Uncle Merry is for. A bit of afternoon curiosity turns into something more when he tells the children of a war between good and evil that has raged since time immemorial, back to the age of King Arthur and much longer ago than that. The map is a copy of an original that Great-Uncle Merry estimates was written by a local Cornishman no less than nine hundred years ago. It is a set of obscure directions to the location of a hidden talisman—implied to be the holy grail of Christendom—that could tip the balance in the struggle between good and evil. It's up to the Drew children to find the grail, but Simon, Jane, and Barney are ordinary kids; do they have what it takes to fulfill an ancient quest?
Great-Uncle Merry insists this is the children's adventure and he will limit his role to that of protecting them. Our three young heroes learn not to trust local adults other than Gumerry; Mr Norman Withers and his sister Polly act friendly at the outset, but Captain Toms's red setter, Rufus, has them pegged from the start as ne'er-do-wells. They are among the evil ones that Great-Uncle Merry warned against, who would use the grail for ghastly purposes, and they must be stopped. There are others, too, with a malevolent eye toward the Drew children, or who would betray them for a bribe. As our trio closes in on a discovery bound to change perception of Arthurian mythos forever, a single chilling question drives their determination: if they don't step up as guardians against the darkness, who will?
Defying death wasn't what Simon, Jane, and Barney had in mind for their holiday at Trewissick, but they sought adventure and now they have it. Their encounters with the enemy are frightening; as Jane says, "It's as if there's someone waiting behind every corner to pounce on us. I only feel safe when I'm in bed." It doesn't feel good to constantly be on the verge of your life ending at the hands of evil people, but is it better to take that risk or stay tucked safe in bed where monsters have no reason to pursue? Great-Uncle Merry lays out the stakes of the endless war between darkness and light: "That struggle goes on all round us all the time, like two armies fighting. And sometimes one of them seems to be winning and sometimes the other, but neither has ever triumphed altogether. Nor ever will...for there is something of each in every man." The good versus evil conflict on a macro scale is mirrored in the heart of the individual, who struggles to tame his or her own darkness but never fully succeeds in this lifetime. To which side will we declare allegiance, regardless of our inability to be perfectly loyal? Simon, Jane, and Barney have made their choice, and so must we all.
Over Sea, Under Stone is one of the first novels I read on my own, so it's special to me. The writing is inconsistent—at times it feels herky-jerky, and the deductions that Simon, Jane, and Barney make as they follow the Cornishman's map are difficult to keep track of—but when the story gets on a roll it's easy to feel immersed in the action. The book ends with a dose of ambiguity regarding its mystical elements. I like Margery Gill's illustrations; her renderings of the sea are sublime, and she infuses each of the three young Drews with personality. I can't bring myself to rate Over Sea, Under Stone higher than two and a half stars, but it's the foundation of Susan Cooper's literary legacy: book two in the Dark Is Rising Sequence earned a 1974 Newbery Honor, and book four, The Grey King, won the 1976 Newbery Medal. What surprises await as the series moves forward?
