Dark Wanderings. The Offworld Chronicles, #5

Deadly swamps, treacherous mountains and murderous enemies, more numerous than one can count, danger continually threatens Simon's team from all sides as they press forward through the White Mountains. And, the further they go, the darker things become. But, that darkness doesn't fall entirely on them, as changes are unfolding within the Syndicate that threatens to rip it apart from within and bring about many positive changes to the planet of Offworld that no one ever expected.
