With Chakotay in command, grief over Janeway's impending death coupled with anxiety brought on by the disappearance of Paris, Kim, and the Doctor forces the crew to take increasingly dangerous actions in order to assure their own survival.

But Voyager doesn't fight alone: behind the lines, powerful forces have allied to give the starship aid. Toward this end, a familiar nemesis - the cosmic meddler Q - sends Paris and Kim on a perilous journey. Elsewhere, the Doctor, trapped in a dimension alien to human understanding, reunites with an old friend to help secure the fates of those he's left behind. A powerful end to the String Theory series by Heather Jarman.
