Earth is home to us, but to others it is a prison planet, where alien convicts are imprisoned in human bodies. Four tales by veteran Cthulhu Mythos authors explore the collisions between humans and unwilling visitors among us. "Broken Singularity" by David Conyers: Former soldier Harrison Peel is resurrected on a vacuum shrouded moon on the edge of the galaxy after a million-year, dead-but-undreaming slumber and forced to repeat the same day endlessly. Why is he ordered to collect alien artefacts and how is his fate entangled with three peculiar incidents in Earth's distant past? Can he break the endless repeating day before he descends into eternal madness?

"The Prisoner from Beyond" by Matthew Davenport: After the Civil War, two surviving members of the Esoteric Cavalry head west to recruit, and tame the land. Barrenstand is a town with a problem, a new man at the edge of town is giving them nightmares ... that bite. Who is the stranger and where, exactly, did he come from?

"Body Snatchers" by David Hambling: In 1920's London, investigator Harry Stubbs is drawn into a case involving an apparent madman with impossible knowledge, and discovers a web of strange sects, multiple identities and an ancient conflict between occult powers, leading to an unforgettable graveyard encounter.

"Leng's Labythinth" by John DeLaughter: Exchange student Francois Delapont is a man on the run. After he witnesses a ritualistic murder in Chartres, inhuman forces pursue him to discover the apocalyptic secrets behind the cabalistic rites he observed. Will he escape them or die during an interrogation that promises to literally turn him inside out?
