Dreadnought! (Star Trek, Book 29)

"Star Empire" is the Federation's most powerful new weapon -- a dreadnought, first in a class of super-starships -- capable of outgunning a dozen Klingon cruisers, or subduing a galaxy. On the eve of her maiden voyage, "Star Empire" is stolen by terrorists who demand a rendezvous with the "Starship Enterprise(TM) " -- and with Lieutenant Piper, stationed aboard Kirk's ship on her first training cruise. Now Piper must discover why her friends from Starfleet are among the terrorists...and why they insist the ship was stolen not to attack the Federation -- but to save it!
