God I hated Dark Tide. If you want to talk Mary Sues in Star Wars (and I absolutely don’t), Corran Horn is in a league all his own.
“Mary Sue”? I haven’t read any other books with Corran Horn, but in Dark Tide he fails pretty spectacularly. In the first book he nearly gets killed at the end and has to be saved, and in the second book he has to leave both the New Republic army and the Jedi Order after he is blamed for the destruction of an entire planet.
