Charity's Cavalier by Isabella Hargreaves

In a nation divided, two enemies are united.

Widowed during the Battle of Worcester, Puritan woman Charity Goodwyn, dares to dream of an independent life, living with her aunt, unbeholden to men. Sir Edward Lovelace, a Royalist, gravely wounded in the same battle, wants to live to serve his king again. Charity's only way to safely reach her aunt is to take the Cavalier with her, disguised as her husband, and helping him escape the Parliamentarian forces. What happens when Sir Edward unexpectedly recovers, surprises and endangers them both.
