Sebastian of Kings Ransom

Can Celeste trust Sebastian in their marriage of convenience which flares with unexpected passion while a threatening presence prowls at night in the old house.  

Celeste Beaumont travels to an isolated vanilla plantation to meet her estranged grandmother. When she arrived she found her dying grandmother whispering fearfully about nightly intruders wandering the rooms of the old mansion. What could they want?  Was her grandmother lucid?

Sebastian Beaumont, an orphan of the city streets and adopted by Celeste's grandparents, seemed to have had the life Celeste's mother should have enjoyed.  Educated in England at a fine school, he returned to manage the plantation. The tall, darkly handsome man did not try to hide his suspicion that Celeste came at an opportune time to grasp her share of the thriving plantation that he had worked so hard to bring to profit for his adopted parents.

The grandmother manipulated the two from the grave, forcing them into a marriage of convenience in order to protect the interests of the plantation. Between Sebastian and Celeste flared an unwanted passion that neither could control.  Although her feelings toward Sebastian blossomed, her trust in him remained divided.  Who was walking through the halls at night and why did Sebastian refuse to believe it?
