Populating options in blueprint

I have a page ‘shop.php’ which lists the titles of books for sale.

I have a section in the homepage where I want to feature two of these books.

I want to create a select field in home.yml which is populated by the titles of the books in the shop. I have used the following query…

         fetch: site.find("shop").children.title

I find that the select field shows the url’s of the books rather than the titles. Can anyone advise me where I am going wrong please?

Pls. check out the docs: Select | Kirby CMS

Thank you, finally got there with the link using…

  label: Category
  type: select
  options: query
    fetch: site.children.published
    text: "{{ page.year }}"
    value: "{{ page.slug }}"
