Come again by Robert Webb

Kate's husband Luke - the man she loved from the moment she met him 28 years ago - died suddenly. Since then she's pushed away her friends, lost her job and everything is starting to fall apart. One day, she wakes up in the wrong room and in the wrong body. She's 18 again - but remembers everything. This is her college room in 1992. This is the first day of Freshers' Week. And this is the day she first meets Luke. But Luke is not the man that she lost: he's still a boy - the annoying 19-year-old English student she first met. Kate knows how he died and that he's already ill. If they can fall in love again she might just be able to save him. She's going to try to do everything exactly the same.
