The 15th Star (A Lisa Grace History - Mystery) by Lisa Grace

Set during the War of 1812:

In the fall of 1809 Grace Wisher, a young slave girl, escapes the plantation to live her life in the port city of Baltimore, Maryland. She is indentured to Mary Pickersgill who teaches her the skill of sewing flags and standards. Yet Grace is hiding a terrible secret, one men will murder for even hundreds of years later.

In the present, Keiko Zorben is finishing her master's degree by working as an intern at the Smithsonian Institute. While archiving mislabeled letters, she finds a clue to the whereabouts of the missing star from the Star Spangled Banner. For over two hundred years its location has been a real-life mystery, until now.

Keiko asks the handsome Dr. Julian Lone Wolf, the head of the American Indian Studies Department, to join her on her search for the missing star.

When a docent is murdered and an attempt is made on their lives, Keiko and Julian realize finding the missing star and the secret it holds, is their only key to survival.

"The 15th Star" by readers as a mix of "National Treasure" meets "1776". Perfect blend of history, mystery, and romance.
