Omega Threshold: Earthrise

Book 4, Predator Space Chronicles - Predator Space Chronicles 4

This book can be downloaded and read in iBooks on your Mac or iOS device.


Amir Tarkos is one of the only humans in the Predator Corp, the most feared and respected military force in the Galaxy. With his partner Bria, a bear-like carnivore, Tarkos is on a dangerous and difficult mission to defend Earth from the last surviving Ulltrians, a race that once extinguished much of the life in the Galaxy.

Tarkos and Bria return to Earth to search for the Ulltrian presence hidden on the planet.  But Earth is in turmoil as opposition grows to the plan to join the Galactic Alliance.  And, thousands of light years away, a young human girl, Margarita Calvino, has uncovered the secret that will enable the Ulltrians to rule the Galaxy.  Tarkos and Bria face the human underground, as Margarita must alone outsmart a hostile alien race.

Omega Threshold: Earthrise is the first half of the novel Omega Threshold.  The book stands alone but--warning--ends in a cliffhanger.  The sequel and resolution, Omega Threshold: Earthfall, will appear in December 2017.

This novel also forms part of the ongoing Predator Space Chronicles, which are told in novels and short stories.
