It worked!

Thanks, chaley. You're awesome.

I tweaked it a little, and here is the complete module code that adds an empty book, in case it's of interest to anyone else:

from calibre_plugins.action_chains.actions.base import ChainAction
from calibre.ebooks.metadata.book.base import Metadata

class AddEmpty(ChainAction):
    name = 'Add Empty'

    def run(self, gui, settings, chain):
        db = gui.current_db
        ids, duplicates = db.new_api.add_books([(Metadata(None), {})])
        db.data.refresh()
        gui.library_view.model().resort()
        gui.tags_view.recount()
        newid = ids[0]
        gui.library_view.select_rows([newid])
