Creator's Pet: Blizzard loves Nova. She's repeatedly emphasized to be one of the most powerful Ghost agents in history, with psionic powers rivaling Kerrigan before her infestation, she received two novels and a graphic novel series focusing on her, and features in Starcraft II in cameos that serve no real purpose except to have her in the game. Yet for all the attention Blizzard gives her, fans have a lukewarm reception and don't care for her.
Novelization First: Starcraft: Ghost had a prequel novelization called "Nova", which was released in 2006, and was supposed to come out simultaneously with the game. The proper novelization called "Spectres" didn't come out until early 2011. And both are apparently canon, given the events of Nova's cameo.
