Feast or Famine (Temeraire #1.5) by Naomi Novik
Blurb: Breakfast in Dover, with complications.
Dragons can be very clever when they’re hungry!
Set between the events of His Majesty’s Dragon and Throne of Jade, Feast or Famine is an amusing side jaunt along the way. Mention of the happenings in this story are made in Throne of Jade so if you don’t read it going in you will want to on the way out.
