The Inheritance Trilogy is a series of military science fiction books written by William H. Keith Jr. that focus on the United Star Marine Corps.
The United Star Commonwealth sends the 1st Marine Interstellar Expenditionary Force (1MIEF) to fight the Xul out in space so as to buy time for the rest of humanity.
Ten years after the events of Star Strike, humans have located the homeworld of the Xul, deep within the Galactic Center.
Worse, the Xul are developing a weapon that can rewrite nearby reality, making targets like starships no longer exist.
The peace mission fails and the Marine forces cause a star to go off course toward the black hole destroying the Xul's dyson cloud.
