Looking for a story

[twat2025]

Looking for a story that i had in my fav;s but cannot find it. It s a recon story that the wife makes a mistake, but she is drugged w/o her knowledge. Then she leaves town and ends up in las vegas, works for a charity, then decides to contact her sister, to find out that they have been searching for her. She comes home and ends up remarrying her husband that was looking for her. I thinks it is by a well known author, and would really like to read it again. Any help would be appreciated. TY Bill
