The Jewels Of Cyttorak — Dean Wesley Smith

THE X-MEN VERSUS A FIGHTING-MAD JUGGERNAUT!

Since bonding with the ruby of Cyttorak, Cain Marko became the unstoppable force known as the Juggernaut -- and one of the X Men's most vicious foes! But an archaeological dig reveals a fragment of the one thing that might be able to stop the Juggernaut: an emerald from the same dimension of Cyttorak.

Now a vicious billionaire named Service intends to gather all the fragments of the emerald, which will grant him absolute power, unless the X-Men can stop him. But each use of the emerald causes the Juggernaut pain -- and he won't stand for it!

Caught between two unbeatable forces, this is one battle the X-Men may not be able to win.
