Black Magic

BLACK MAGIC -- Book 1 of the Black Magic trilogy:

Inessa Black and her twin sister, Galina, are young college students living in Denver. When Galina is murdered, Inessa is left with only a numb void and nothing left to live for.

The physicist, Dr. Hans Rasmussen, executes a bold science experiment designed to test the very fabric of the universe. But he produces a monster that nobody can control, not even him, its creator. The interdimensional beast is loose, growing, and becoming more powerful with every killing.

The United States is at war for its very survival as interdimensional forces lay waste across the heartland. In the middle is a small-town sheriff, Roy Freeman, who must decide whose side he is on, and if fighting the monster is even possible.
