Vonda McIntyre is a favorite author, but let's be honest, she create entire sections of the Trek novelizations out of her own ample imagination.
There's absolutely no on screen evidence that Saavik is part Romulan.
There isn't any on screen evidence that Saavik was half Romulan, true, but it's so well developed in the novels and comics, I accept it as hard canon. I believe it was intended in the scripts, wasn't it, and just cut out. Is that true or has my imagination run away with me? If so, I wonder if either Alley or Curtis were given any acting instructions on the subject? I do remember hearing Curtis talking about being instructed to play Saavik less emotional.
