Search - Abode of Life (Star Trek Novel, No 6)

#6 in series: The citizens of Mercan cannot conceive of worlds beyond their own. Their sun, Mercaniad, is prone to deadly, radioactive flare-ups, and the Mercans have organized their life around the need to survive The Ordeal--until a strange visitor appears from out of nowhere...
The Enterprise, badly crippled and in desperate need of repairs, must seek help from a people who cannot believe in its existence. Mercaniad is about to blow, and James Kirk faces an impossible choice; to attack the sun itself and save his ship and crew--or let a people live in peace, in the only world they know...
