Scimitar's Glory — Dietmar Arthur Wehr

Human-explored space lies between two alien races that are either openly aggressive or covertly hostile. 7th Fleet discovers that one of those races is moving to attack. In a moment of panic, the commanding admiral orders the fleet to attempt a risky jump through hyperspace. They miss hitting their target star''s gravity well and end up deep in unexplored space with a shockingly long trip home and not nearly enough food to last that long. With war now raging in their home systems, the officers of 7th Fleet must find a way to put aside their egos, ambitions, and fears in order to make it back, and they know that not all of them will. 

Scimitar''s Glory is the first book in a new, fast-paced, action-packed military SF series: Swordships Odyssey. The second book, Excalibur''s Quest, is also now available.
