Coming off of that challenge, ready to go with a view that allows for creation of a book, let’s write a method that will add that new book to our library.

  var sortedBooks: [Book] { booksCache }

  func addNewBook(_ book: Book)

  /// An in-memory cache of the manually-sorted books that are persistently stored.
