Delta Search
Young Jim Endicott has but one dream -- to attend the Solis Space Academy, the gateway to the stars and the far-flung civilization known as the Confederation. But unbeknownst to Jim, he has a secret encoded in his DNA. A secret that threatens an empire.Jim's Academy application sets of an explosive chain of terror, hurling the young man into an adventure beyond his wildest dreams. With the help of a beautiful fellow outlaw named Cat, who is as tough as she is tender, Jim begins to unravel the shocking truth about his own origins -- and uncovers the fatal deception that has split a bitter humanity into warring factions bent on mutual annihilation.

In Alien Hands
Jim Endicott is a man with a secret--hidden even from himself. Encoded in his DNA is a cybernetic weapon that can alter the balance of power in the Galaxy--for good or evil. But all Jim knows is that his dreams are shattered and he must take destiny into his own hands as a mercenary, a warrior for sale to the highest bidder.
The dreaded Hunzza fleet, the deadliest armada in the Universe, is armed to destroy Jim's home planet and the star that gives it life. Now, Jim must discover the truth about himself and decide which side he's really on, for the secret in his DNA is the only force that can save the galaxy before it's too late!

Step Into Chaos
After defeating the dreaded Hunnza fleet, Jim Endicott wants a "normal" life. But his wish is not to be, for a new and even more terrible conflict is stirring. Earth's former ally, the Alba Packlord, suspects that humans are about to "Leap"--transcend to another level of existence in a process that will sweep away star systems, laying waste to the universe. To eliminate the human threat, the Packlord has made a secret alliance with the Hunnza--but not if the mysterious immortal known as the Outsider can stop them using Jim as a weapon. First, though, the Outsider has to find his embittered hero. Distraught over the death of his father, Jim has plunged deep into the underground, where danger of another kind lurks in the shape of a girl as bad as she is irresistible. But the Packlord will stop at nothing to succeed, including assassination. Jim's only hope for survival lies in making the Leap himself: taking the step into chaos that will save humankind or turn the universe into a graveyard of burned-out stars.
