In the 35th century, mankind has colonized vast reaches of space, yet war remains constant as galactic governments and interstellar corporations fight for control of resource-rich planets and lucrative interstellar trade routes. And if centuries of war has taught man one thing, it’s that planets are valuable and lives are cheap.

“War’s Edge puts the military back into military science fiction, in what is destined to be considered a classic along the lines of Starship Troopers, Dune, and The Forever War. Gritty action, military realism, compelling science fiction, and believable characters make this book a must read for sci-fi fans. “

Nathaniel Timberlake


Galactic war. On its heels after the disastrous Battle of Verdant, the United systems Alliance is taken completely by surprise when the Galactic Union launches and all-out surprise offensive that captures planet after planet. Fear and panic spread like an oxygen fire as the Union invasion fleet makes a dash for the Alliance core worlds.

“Bolder and more action packed than anything Ryan Aslesen has written before, this groin kicker of a book is the furthest thing from a bland, spineless sequel: it’s a brutal, intense successor to the initial scifi masterpiece.”

Nathaniel Timberlake



A War’s Edge Stand Alone Novel

The most dangerous job in the galaxy. In war, there is no second place, planetary governments employ private armies to help fight their battles.

War Whore is a lean, mean, thrill-a-minute machine that goes from zero to sixty in no time flat…The book is the literary equivalent of a drag race; it gets going quick and keeps it comin’ fast and furious all the way to the explosive (and unexpected ending). This is Aslesen at his best.”
