Astonishing X-Men, Vol. 3

The X-Men return to base, giving Beast the Ghost Box they found by Subject X. Beast calls in Abigail Brand for a consultation, which reveals the true nature of the Ghost Box, which explains some of the mysteries they've found about Subject X and the dead man. Brand and Wolverine use their intelligence knowledge to track down the next likely stop: a five mile stretch of Chinese jungle that was impervious to all outside scanning. It seems, however, some Earthly forces were able to penetrate nonetheless.
