Having rescued her husband Gregory from captivity in France, Margaret looks forward to an uneventful life in the English countryside. But Gregory's meddling family, a greedy abbot, and an ancient, supernatural creature that's been roused from a spring in the center of a disputed woodland dash Margaret's hope in this final book of Riley's trilogy.
The final adventure in the beloved and bestselling Margaret of Ashbury trilogy, which began with A Vision of Light and In Pursuit of the Green Lion.

Margaret of Ashbury is ready to settle down; the medieval healer is looking forward to an uneventful life in the country. And, indeed, life with her true love and a brood of rambunctious children is nearly perfect--except for her husband Gregory's ever-meddling family. Finding himself deep in debt once again, Gregory's father has plotted to sell Margaret's daughter off in marriage to save his woodlands from a greedy abbot. In a panic, Margaret turns to her old friend Brother Malachi to help save her daughter by whatever means necessary. The tension within the feuding family rouses an ancient being that dwells in a spring at the center of the disputed woodland. The watery creature has its own plans, and its eye is on Margaret's infant son.

Favorite characters return, the stakes are high, and the air is thick with intrigue and danger. Written with the historical accuracy, supernatural plot twists, and humor that Riley's readers have grown to love, The Water Devil is a high-spirited adventure that brings Margaret's odyssey to a satisfying conclusion.
