My wife gave me the Hornblower series for Christmas, and I’ll get at them soon. (I have read them all, but not for many years.) The Patrick O’Brian books are great, though it might be a bit daunting to read them all in a row.
Try some of Kenneth Roberts’s historical fiction, like “Rabble in Arms” or “Lydia Bailey”.
“Oliver Wiswell” had a unique story told from the Tory side.
