Maven Fairy Godmother: Through the Veil by Charlotte Henley Babb

A dead cellphone calls with a job offer and a promise of dragons. Imagine if Terry Pratchett sat down with Kathy Bates to make up fractured fairy tales for Edward Everett Horton to read aloud: you’d get MAVEN FAIRY GODMOTHER: THROUGH THE VEIL. Down and out, Maven Morrigan is ready to give up what’s left of her self-esteem for a cup of coffee when her last chance to redeem her life comes as a job offer as a fairy godmother. But Faery is shrinking, the other fairy godmothers have disappeared, and nothing she does turns out right. How can she put together the happily-ever-after each of her clients wants with her boss standing in her way?
