Michael - Zodius, #1

HE IS A LETHAL WEAPON... One of an army of soldiers created by a government experiment, Michael is different from the others involved, dangerous in ways no one quite understands. Even Michael himself, believes darkness lives within him, evil fights to control him. And only one woman, the woman he loves, can bring him back from the darkness and into the light. But she has become his enemy. Cassandra is the daughter of the man who created Michael, who unknowing to her, tricked him into taking drugs he believed to be immunizations.
She is torn between her love for Michael, and her love for her father. She's also the woman Michael left behind, breaking her heart, seeming to shut her out without looking back. But now Michael is back, fully intending to show his enemies, Cassandra's father included, his wrath. And he's not leaving without Cassandra.
