The Mediator #4: Darkest Hour

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?
