The Romulan Way (Star Trek: The Original Series, No. 35)

254pp. They are a race of warriors, a noble people to whom honor is all. They are cousin to the Vulcan, ally to the Klingon, and Starfleet's most feared and cunning adversary. They are the Romulans -- and for eight years, Federation Agent Terise LoBrutto has hidden in their midst. Now the presence of a captured Starfleet officer forces her to make a fateful choice - between exposure and escape. Between maintaining her cover - and saving the life of Dr. Leonard McCoy. Here, in a startlingly different adventure, is the truth behind one of the most fascinating alien races ever created in STAR TREK -- the Romulans.
