Long was a female Human officer in Starfleet in the 24th century. As of 2381, she held the rank of captain, and was commanding officer of the USS Massachusetts. That year, the Massachusetts was assigned to Vulcan. While there, ship's counselor Kaimi Pumehana was asked to help care for a number of civilian Vulcan patients from a hospital in Vulcana Regar, following the murder of a Vulcan counselor there. Distrusting the security situation at the hospital, Long had Pumehana's new patients transferred up to the Massachusetts during their treatment. (ST novel: A Singular Destiny)
