I have been looking for this book forever. I can't remember the title or the names of the main people. BUT it is a historical romance novel. Its about a girl that finds out her sister is dead, everyone thinks she killed herself and her baby but the sister doesn't believe it. So she pretends to be this guys cousin-in-law that he never met and moves in with them. SHe knows her sister spent a lot of time at that house. She falls in love with this guy and finds out her sister was having an affair with his brother and his wife ended up killing her sister. Very twisted but I loved it and now I can't find it. Please help! I think the brothers name was Charles or something like that and the heroine had a name like coreen but I could be way off.
