query GetBooks {
  books {

  }
}

Start with query GetBooks { and inside it add books { }.

2

Inside the books field, add the title field to request the book titles.

GraphQL

query GetBooks {
  books {
    # Add the title field here
  }
}

Need a hint?

Inside books { }, add a line with title.

3

Add the author field

Add the author field inside the books field to request the author names.

GraphQL

query GetBooks {
  books {
    title
    # Add the author field here
  }
}

Need a hint?

Inside books { }, add a line with author below title.

4

Complete the query

Make sure the query is complete with matching braces and no extra fields.

GraphQL

query GetBooks {
  books {
    title
    author
  }
}
# Query complete

Need a hint?

Check that all braces match and only title and author are requested inside books.
