I am looking for a Christian book that I read last year.?

The female character was an author. She wrote about her son in a parralell way. He was in her world but in the book he was in another world. She was trying to show him that he was lost because of his drug use. Don't know her name or the title but would like to find this book again.I am looking for a Christian book that I read last year.?
