FEAR THE DARK.   The crew of the Artemis - led by Firewatch agent Alexandra Petrova - have survived the furious onslaught of the Basilisk and broken through the space blockade around Paradise-1. Now they can pursue their original mission and investigate why Earth's first deep space colony has fallen silent.     The answer seems obvious: the site is deserted.   Or so they think.   Some of the colonists remain . . . but they're no longer human.   Petrova and her crew now face a desperate struggle to survive as they attempt to uncover the mystery of what has befallen the colony.   If they fail, the darkness that has fallen over Paradise-1 will consume them.
