All three are based on/written by JMS, so all of them are as canon as the (canon /ubbthreads/images/icons/smile.gif) novels. The only one I have (as of yet) is the second GN, Shadows Past and Present. The premise: Keffer (remember him) and Garibaldi go on a mission to investigate Londo's activities; Morden hears of this and a Shadow ship shoots them down. Garibaldi rembembers his past, flashing back to his first meeting with Sinclair on Mars. Garibaldi's art in this section is TERRIBLE. He has purple hair. Yeech. Anyway, Sinclair and Garibaldi's shuttle crashes (can you say, Shadows) and they infiltrate a Psi Corps/Shadow base... ooh, and there's one surprising twist on the last page that I haven't really figured out yet... /ubbthreads/images/icons/grin.gif</font></td></tr></table>

I'll review IVN in a week, when it arrives from the UK. I'll buy Prive of Peace soon, and review that too.
