I really enjoyed the archaeological aspects of this novel--how things can be preserved in the peat for hundreds of years, and how, once found, they offer a doorway into the past. I also loved getting to know Ireland a little better--glimpsing part of its history and culture, even its music. But it's the mystery surrounding Mina's disappearance that drives this novel. Haunted Ground is well-plotted and well-written, with likeable characters. (Especially 39-year-old flute-playing Cormac with his dark brown hair, intense dark eyes, and lean rower's build, and his love of the past.) There were a few coincidences at the very end surrounding the red-haired girl from the bog that felt just a little too neat and convenient, but that didn't stop me from enjoying this book. It's an interesting mystery; plus, it's set in Ireland...what more could you possibly want?
