The New Frontier [abridged]

Sector 221-G: For the whole of Federation history, this large
area of space has been controlled by the Thallonians, a cruel,
militaristic race of which little is knownexcept that they rule
the other races in their sector with vicious iron hand.

Now the Thallonian Empire has collapsed and the systems it once
ruled are in chaos. Old hatreds are surfacing. Petty tyrants
control deadly weapons. World after world is descending into
disorder and self-destruction. The Federation must send a
starship to help where it can and report what it finds.

That ship is the U.S.S. Excalibur, a newly refit Ambassador-class
starship commanded by Captain Mackenzie Calhoun and manned by
Starfleet's best and brightest, including some old friends from
Star Trek: The Next Generation and some of the most dynamic new
characters ever to crew a Federation starship.

Join Captain Calhoun and the crew of the U.S.S. Excalibur as they
explore strange new worlds, seek out new life and new
civilizations, and boldly go where no one has gone before!
