Three children on a holiday in Cornwall find an ancient manuscript which sends them on a dangerous quest for a grail that would reveal the true story of King Arthur.

"Laura Callaway daily walks the windswept Cornwall coast, known for many shipwrecks but few survivors. And when a man with curious wounds and an odd accent is washed ashore, she cares for him while the mystery surrounding him grows. Can their budding attraction survive, and can he be returned to his rightful home when danger pursues them from every side?"--

"Manna from Hades" is a confounding case of daring theft, double-cross, and awily older woman confronted by a case of murder most foul.
