In 1776 London, orphaned vicar's daughter Amaranthe Illingworth supports her small household with her skills as a copyist, but her quiet routine is shattered the day three children show up at her door seeking aid from her brother, their tutor. Behind them storms in Malden Grey, would-be barrister and their erstwhile guardian, who accuses Amaranthe of kidnapping the young Duke of Hunsdon and his siblings.

The former duke's illegitimate son, Malden Grey has learned to live by his wits, and he's told he'll advance to the bar if he takes a proper wife. As she helps him restore order at Hunsdon House, Amaranthe seems a likely candidate-if only Mal can unearth the truth behind the rumors that she's been forging, and selling, priceless medieval manuscripts.

Amaranthe, in the meantime, needs to stay on her guard lest the charming Malden Grey steal her heart at the same time she's hoping to borrow from his library a priceless book that could make her fortune. But when Mal's foray into Amaranthe's past yields a discovery that will change both of their destinies, they'll have to fight together to clear their names and stake out a future together-if either has a future at all.
