The Quiet Place (Star Trek: New Frontier, #7)

Ever since the fall of the Thallonian Empire, Si Cwan has been searching for his younger sister, the only other survivor of the royal family. His quest has been a hard one, filled with many disappointments, but now it may be nearing its end.... On the planet Montos, a mysterious young woman, whose past is shrouded in secrecy, finds herself pursued by both the fanatical Redeemers and a vicious race of feral predators known only as the Dogs of War. All are in search of information regarding the true nature and location of the Quiet Place, a mystical realm celebrated in myth and legend. Only this same woman, now called Riella, may hold the secret of the Quiet Place, a secret that the Redeemers and others will kill to possess.

Is Riella indeed Si Cwan's long-lost sister? Before he can learn the truth, he and his crewmates must brave the unchecked savagery of the Dogs of War -- and enter the terrifying heart of the Quiet Place.
