...a spellbinding time travelogue.

The Wall Street Journal
In a high-voltage jolt of insight, Mr. Raffles converts what might seem a dry scientific concept into a potent literary metaphor to help anyone whose sense of time has been fractured by loss.
Jeffrey Meyer,
Library Journal
A work of poetic science, a smashing together of the human and the natural world, of cultures separated by time. Just as a geologic unconformity, this is erudite and artistic..

Each section is packed with vivid, entertaining tales, whether Raffles is discussing the enigmatic objects, obscure rites, the Scandinavian occupation of the Orkney Islands, or the geopoetics of megaliths. Throughout, the author is 'alive to the deeply archaic currents moving through and around me.” The text shimmers with rangy curiosity, precise pictorial descriptions, well-narrated history, a sympathetic eye for the natural world, and a deft, light scholarly touch. The mood is as unpredictable as next week’s weather, as Raffles remains keenly attuned to the politics and personalities that move the action along.
