Some battles are fought in boardrooms. Others are fought on one's knees.

Answering a calling is one thing. Remaining faithful to it is another.

Peter Reinold believed that chapter of his life had been closed forever.

Years of quiet fidelity had patiently shaped him into the man he had become. The ambitions of his former life had long since been surrendered. The promises had been made. Peace had finally been found.

Then tragedy calls him home.

When a devastating accident leaves his brother fighting for life and his family's international shipping empire facing an uncertain future, Peter returns to the world he believed he had left behind. He tells himself it is only for a season-long enough to steady his inexperienced younger sister, fulfil a duty born of love, and quietly return to the vocation that has become the very foundation of his life.

But some doors never close as completely as we imagine.

Old friendships. Old responsibilities. Old affections. None of them is evil. Each is worthy. Each asks something of him. Each reminds him of a life that might have been.

Then another plea for help arrives.

A gravely ill young woman has become the centre of a terrifying mystery that medicine cannot explain. As Peter confronts an ancient enemy armed only with faith, prayer and years of spiritual experience, he discovers that the fiercest battles are seldom fought before the eyes of the world...

...they are fought within the human heart.

When every path leads toward something worthy of love, how does a man remain faithful to the highest good? And what becomes of him when every lesser good pleads to be chosen first?

Vocation of a Gadfly, the second novel in The Gadfly Saga, is a literary novel exploring fidelity, sacrifice and the enduring cost of promises made for life-revealing that the greatest battles are rarely fought against evil alone, but within the struggle to love what is highest above all that is merely good.
