The Long-Range War - A Learning Experience, #5

The gloves have finally come off ... The Tokomak, the unquestioned masters of the galaxy, have dispatched a massive fleet to crush the Solar Union - and the fledgling Galactic Alliance - before the human race and its alien allies can tear the galactic order asunder.  Hundreds of thousands of starships under the command of an alien tactical genius, bent on exterminating the entire human race ... the darkest hour is truly at hand.
Admiral Hoshiko Stuart has a plan.  The Solar Union will dispatch a fleet of its own, with the objective of smashing the alien fleet before it reaches Sol.  But, as human technology clashes with alien treachery, experience and sheer numbers, it becomes clear that there can be only one victor ...... And whoever loses will lose everything.
