We Lead - Ark Royal, #9

The conclusion to the third Ark Royal trilogy!The Second Interstellar War - pitting humans and their Tadpole allies against an enigmatic alien empire - appears to have stalemated.  Neither side can push through to the other's core systems without risking substantial losses, neither side can gain a decisive advantage.  But when a brilliant human scientist invents a way to jump across the stars without a gravity tramline, an opportunity arises to strike the enemy in their undefended rear.  It is an opportunity that cannot be allowed to pass.
Now, HMS Vanguard and her crew - and the largest fleet ever assembled by the nations of Earth - heads out on a do-or-die mission to challenge their enemies to one final battle ...... And if they lose, they will never see home again.
