Rosie's Revenge — Suzanne Floyd

When Parker Evans inherits a farm from a great-aunt she never knew, she is confronted with a past she knew nothing about, finds a new home, a grandmother who loves her, unearths the answers to a sixty year old mystery, and finds a love directed from beyond the grave.
In order to inherit the farm and all that goes with it, Parker must live in the house for a year: a house with no electricity, running water or bathroom. While living there she can modernize it, but she can't move out. Her great-aunt, Rosie, has already selected a handsome contractor, and has drawn up the plans, all Parker has to do is approve them. There is no explanation why Rosie left all this to her instead of her own brothers.
Curious about the family she never knew, Parker decides to stay, at least temporarily, and is confronted with her hostile grandfather who would do anything to chase her away, and gain control over the land he considers his birthright.
Just walking through the small town proves to be an obstacle course as people step off the sidewalk to avoid her, or run off the road as they stare at her. Rumor has it Rosie has come back to haunt them.
While work continues on the house, Parker discovers the journals Rosie kept from the time she was a little girl, telling of her life with an overbearing father and four brothers. Rosie also left letters to Parker instructing her to trust Shep Baker, the contractor, and to find out what happened more than sixty years ago, deepening the mystery for Parker.
Shep is a slow talking cowboy with a mystery of his own. His grandfather was adopted as an infant, and Shep is looking for his extended family. But why did Rosie take such a liking to him when she was so nasty to others? Just more questions for Parker to find the answers to.
The answers to her questions are in the journals, but finding the answers could prove fatal.
