The Relentless Warrior is Book Six of the Star-Crossed Series.

Jericho Bentley is disillusioned by life. He feels lost in a world of peace and restless in a time threatened by war. He has given up on love, forgotten how to trust others and decided a lifetime of bachelorhood is all that remains for him.

Olivia Taylor was struggling to find her way in a human world. Now taken from the only life she's ever known and changed on a molecular level, she is more lost than ever. With her sister struggling to survive the after effects of one of Dmitri Terletov's experiments, Olivia sets off with Jericho to find a cure for both herself and her sister.

Together, Jericho and Olivia find more than vengeance and answers, they find a deep friendship that might teach them both to trust again. Maybe even to love again. As long as they can both put the hurt of their past behind them for good.
