The Ministry of Time

A civil servant is assigned to help a real historical Royal Navy commander, rescued from the doomed 1845 Franklin Expedition to the Arctic. Her job is to help him adjust to modern life. Teach him about electricity, supermarkets, bicycles, the internet. File reports. Keep it professional.
It does not stay professional.

Part time travel romance, part spy thriller, part workplace comedy, part meditation on displacement, empire, and what it means to belong somewhere that was never built for you.

Winner of the Goodreads Choice Award for Best Science Fiction. Hugo Award finalist. 339 pages.
