The Avalon Chanter — Lillian Stewart Carl

Archaeologist Maggie Lauder has personal reasons for proving Farnaby Island is the Avalon of Arthurian legend. But when she opens a tomb in a medieval chantry chapel, her plans go awry.

The story Jean Fairbairn planned to write is shadowed by a contemporary investigation. Her husband, ex-cop Alasdair Cameron, has a history with the investigating detective, if not as long a history as Maggie does.

They are stranded on Farnaby, caught in the conflicting loyalties of its inhabitants, trusting only each other--until they find themselves on opposite sides of a cold case turned scorching hot.

Northumbria, between England and Scotland, the uncertain shore where this world fades into the next, bagpipers play laments on their chanters, and ghostly plainchant echoes in the fog.

It's April in Avalon.
