ROLLING THUNDER (Wings of War)
They were America's bravest men - seasoned veterans and young daredevil pilots with dreams of glory in the air...Court Bannister, an Air Force captain overshadowed by his famous father, driven to prove his worth to his comrades - and himself...Toby Parker, the brash first lieutenant who gambled his innocence in the flames of war...and Wolf Lochert, the Special Forces major who ventured deep into the jungle to rescue a downed pilot - only to discover a face of the enemy for which he was unprepared.
Rolling Thunder is an explosive portrait of men at war, so authentic and powerful, only a veteran pilot could have written it.
It is the first of the five-book Rolling Thunder series. Next are Steel Tiger, Phantom Leader, Eagle Station, and Storm Flight.
"A taut, exciting tale of good men in a bad war. Berent is the real thing." --- Tom Clancy
"Rolling Thunder is terrific - a novel of exceptional authenticity that hits like a thunderclap. A decorated Vietnam pilot, Mark Berent knows planes and men and battle, and he whirls them around in a story of uncommon strength." W.E.B Griffin

Rosetta (Jim Meade: Martian P.I)
Murder, betrayal, the fate of Humanity... it's all in a day's work for Jim Meade: Martian P.I.
In a slow orbit around the sun, just beyond Mars, a mining colony known as Rosetta houses thousands of Consortium citizens who mine the valuable ore Humanity uses for space travel. Over the last three years, Rosetta has grown exponentially, from a tiny mining colony, into an economic behemoth that threatens the delicate balance of power between The Consortium and Coalition - two nations who are still healing from a devastating nuclear war that turned Earth into a hellscape of hopelessness and despair.
After a prominent scientist for The Consortium dies in an apparent accident, Jim Meade is hired by the victim's family to find out what really happened to their father Dr. Sanjay Sinjakama. There, Meade finds himself caught up in a power struggle between the diabolical CEO of Nebula Mining Dimitri Koschei, and Lazarus Rincon, the charismatic leader of a vicious cult.
With the assistance of his friend and confidant (the beautiful Emeline Hunan), Meade races against the clock to find Sinjakama's murderer and prevent a catastrophic disaster that might mean the end of all life on Earth.
