Shades of Time - The After Cilmeri Series, #12

March 1294. With David and Llywelyn in Ireland, the rule of Wales and England has fallen to Math and Anna. Unbeknownst to them, however, rebellious barons have tried to assassinate David and thrown Ireland into civil war. When the treachery reaches across the sea and touches Anna, she finds herself at the center of a conspiracy that stretches from Dublin to Edinburgh-and only her actions and choices stand between her family and the destruction of everything they've worked so hard to build.
