Now, trapped deep underground, Storm battles her claustrophobia while trying to find answers - and as natural phenomena tear apart the desert, the X-Men race to uncover the truth and save their teammate! While some of the X-Men follow a lead that takes them to the Inhuman Queen Medusa, Psylocke makes an explosive discovery of her own! Reliving history, can the X-Men find a way to win the day this time around - or are they doomed to continue making the same painful mistakes? Collecting X-MEN (2013) #23-26.
