Avenged (The Arnaud Legacy) by Lynn Carthage
Long ago I was a servant girl at the great manor house in the quiet English villageof Grenshire. My mistress, Madame Arnaud, proved cruel, and many died at her hands.To stop her, I tried to kill her. I failed. And I lost everything. But that was then. Now, Phoebe Irving's family has moved into the Arnaud Manor.Phoebe, her friend Miles, and I crossed paths and discovered a powerful connection.Together we might be strong enough to untangle an ancient prophecy hanging over thistroubled place where old, deep magic mingles with greed and revenge. We might save Phoebe's baby sister and other innocents. We might even save ourselves.
I thoroughly enjoyed the conclusion to The Arnaud Legacy Trilogy. Three ghosts are trying to work together in order to fulfill a prophecy written in an English dialect so old google translate won't work. The author did a great job in how her characters interacted with each other through dialogue, body language and flashbacks. Their interactions with people and how that could happen was done on a level that could be 'believable' given the material. It was a very satisfying conclusion to a well thought out trilogy and I particularly enjoyed the surprise twist connected to one of Britain's best histories.
