The Illustrated Guards! Guards! Pratchett Terry (2020)

This is where the dragons went. They lie therenot dead, not asleep, but dormant. Although the space they occupy is not like normal space, they are nevertheless packed in tightly. They might bring to mind a can of sardines, if sardines were huge and scaly. And somewhere, presumably, there is a key to let them out. Captain Sam Vimes of the Night Watch is going to have one extraordinary night when that happens.
