I. M. Foster is the pseudonym for award-winning author Inez Foster, a historian and librarian who loves to read and write and search around for her roots, genealogically speaking. She has a BA in History and an MLS in Library Science and enjoys the research almost as much as she does writing the story. In fact, many of her ideas come to her while doing casual research or digging into her family history.
Under the pen name of I. M. Foster, she is the author of her South Shore Mystery series set in the early 1900s in a small village on Long Island. Inez also writes a historical time-travel romance and a paranormal time-slip romance under the pseudonym Andrea Matthews. Her Thunder on the Moor series is a tale of Border Reivers and forbidden love, set on the turbulent border between sixteenth-century Scotland and England, while her Cross of Ciarán series follows a fifteen-hundred-year-old Celt who finds himself in the twentieth century, falling in love and trying to navigate a new world.
As well as being a member of the Author's Guild and the Alliance of Independent Authors, Inez is also a member of the Long Island Romance Writers, the Sisters in Crime, and the Historical Novel Society.
