I never read Jedi Prince, I know they are kinda rare and expansive, kinda like Galaxy of Fear, and Junior Jedi Knights. But if I remember correctly, Jedi Prince was the one with the Imperial posing as Palaptines son and rightful ruler of the galaxy, while holding his real son, (a deformed man with 3 eyes,) as a prisoner. And I think he had a token from Darth Vader, his glove, but here I might mix up things.
