Meanwhile, curator Lana Gray is fighting to keep the US PANAM John Muir—and the remnants of its crew—alive. Their space capsule housing Yosemite National Park was hijacked. The hijacking turned ninety-five percent of her crew into nightmarish creatures called mourners who flay, dismember, or decapitate with nothing more than sharp-pitched shrieks.
Now, despite their differences, Lana, Tuck, and their crews must work together to save the John Muir. In space, nobody can hear you scream...but on the John Muir, the screams are the last thing you'll hear.
