If Beatrix has 30 books, Alannah has 30 books + 20 books = <<30+20=50>>50 books.
Queen has 1/5 * 50 books = <<1/5*50=10>>10 more books than Alannah.
The total number of books Queen has is 50 books + 10 books = <<50+10=60>>60 books.
All three have 60 books + 50 books + 30 books = <<60+50+30=140>>140 books together
