You don't know what's coming...

Humanity is in danger...

The Krah have found our weaknesses, and nothing will ever be the same.

An experimental device was used in a last ditch effort to save the crew of the Modulus Echo. The result was more deadly than anyone anticipated.

A portal has opened to a new galaxy, a tunnel connecting two distant points of space. It is a doorway to a place ruled by a cruel, militant race whose only focus is complete domination. Humanity knows nothing about the Krah Empire, but soon they will learn to fear the alien ships and the fierce warriors who crew them. For the first time in the history of the human race, mankind is no longer the most intelligent and powerful species in the galaxy. The first shots in a galactic war have been fired, and the Modulus Echo is on the front lines.

The fourth book in the best selling Kestrel Class Saga, Modulus Echo continues the story of Ben, Kim, Nance, and Magnum as they make their way in the galaxy, doing their best to stay alive and keep flying. Modulus Echo is a fast paced Space Opera in the tradition of Firefly, Ender's Game, and Star Wars, from prolific author Toby Neighbors.
