The Royal Accountant is a historical romance set among the gyesa, the accountants of Joseon's treasury ministry. A woman who forges ledgers and a man who believes numbers cannot lie set out to expose the corruption draining the national coffers.
Song-i lost her parents to war and was taken in by a merchant house. She has a rare gift for figures, but as a woman she can leave no name behind, so she keeps double ledgers from a corner of the shop. Blackmailed by a treasury official, she sits the state examination for accountants and places first.
The man who championed her paper is Baek-ha, a young treasury officer who holds that numbers never lie and neither should those who handle them. But the first task waiting for Song-i at the palace is a false ledger, drawn up to siphon the treasury under the cover of a state banquet.
The first woman among men who have never allowed one, and two people who stood on opposite sides of the same numbers.
