Further: Beyond the Threshold

Stone soon finds himself commanding the maiden voyage of the first spacecraft to break the light speed barrier: the FTL Further. In search of extraterrestrial intelligence, the landing party explores a distant pulsar only to be taken prisoner by the bloodthirsty Iron Mass, a religious sect exiled from the Entelechy millennia before. Now Stone and his crew must escape while they try to solve the riddle of the planet's network of stone towers that may be proof of the intelligence they've come to find.
