And what is he making? Struggling against ancient mystical forces, Tony battles an ancient winged calamity with the lives of everyone at Stark Unlimited hanging in the balance! Plus: When Tony tells Carol Danvers he can't be her AA sponsor because he may or may not have fallen off the wagon, Captain Marvel doesn't take it well. What is Iron Man's new high-tech solution for sobriety? It might be his worst idea yet! Featuring the villainy of the all-new Spymaster! And Jocasta goes all in for 'the ultimate upgrade!'"--Provided by publisher.
