Darkest Hour (The Mediator #4)
When the nineteenth--century ghost of Maria de Silva wakes her up in the middle of the night, Suze knows this is no ordinary visitation -- and not just from the knife at her throat, either. In life, Maria was the fiancée of Jesse -- the same Jesse who was murdered a hundred and fifty years before. The same Jesse Suze is in love with.
Maria threatens Suze: The backyard construction must cease. Suze has a pretty good idea what -- or rather, who -- Maria doesn't want found. But in solving Jesse's murder, will Suze end up losing him forever?
