(The second book in the Mesklinite series)
A novel by

 
 
Shrouded in eternal gloom by its own thick atmosphere, Tenebra was a hostile planet..a place of crushing gravity, 370-degree temperatures, a constantly shifting crust and giant drifting raindrops. Uncompromising - yet there was life, intelligent life on Tenebra.
