I’m looking for a book that is about a nurse caring for a young man (he might have been a doctor) who is dying of complications from measles.  He is in a coma. I think it takes place in Ireland.  The nurse has substance abuse issues, works mostly at night.  He is in love with her and makes up stories and conversations in his head.

I am looking for a book about an Irish widow of a mobster who fakes her own and her granddaughter's death to hide them from her son who has taken over his father's business. She hires an American ex-cop as a bodyguard. The author might be Nora Roberts. If not, it is very much like her writing style. I seem to remember Irish magic being part of the plot.
