X-Men The Hidden Years #16

In "Echoes of a Lost Generation," the X-Men return to the mansion to find Havok and Lorna missing—only to learn they’ve vanished into the Himalayas. With the team racing to track them down, they face unexpected dangers, including a boulder attack that brings them crashing to the ground, and a shocking encounter with the Inhumans and the mysterious First Line. Written and illustrated by John Byrne, with colors by Greg Wright and lettering by Byrne, the cover by Byrne captures the urgency of the mission.
