A Romantic Suspense Series by Gethyn Jones

Love brought them together. Revenge will do anything to tear them apart.

Laura O'Brien is a wealthy Irish widow trying to rebuild her life after devastating loss. Ali Kurmi is a talented younger songwriter, fighting to escape the control of a powerful father and make a future on his own terms.

When music brings Laura and Ali together, neither expects the depth of the connection they find - or the resistance it will provoke.

Because Laura's stepdaughter, Stephanie O'Brien, has never forgiven her for marrying Stephanie's father, the billionaire Irish racehorse breeder Frank O'Brien. Convinced that Laura stole the life and inheritance that should have been hers, Stephanie's resentment grows into a relentless, dangerous obsession.

Set between rural Hampshire and the dramatic landscapes of Ireland, the Fatal Equation trilogy is a compelling blend of heartfelt romance, age-gap love, found family, ambition, music, jealousy and escalating revenge.

For readers who enjoy emotionally rich love stories with genuine warmth - and a dark, page-turning edge.

Why Readers Love This Page-Turning Romance

"A welcome breath of fresh air in these frantic times - a moving tale of love that triumphs over pervasive greed and preposterous revenge - a celebration of friendship and friends who stand by each other whatever the odds - AND a fitting musical soundtrack."

S.D.S.

"An intertwining tale of a love that doesn't conform to society's self-limiting rules - Add in tales of the music business and some unhinged family members and you have a love story which is just so much more than most in this genre. A very entertaining and well-characterised book which had me guessing until the end."

Richard

"What sets Fatal Equation apart from other age gap romance novels is its fast-paced action, unique plot, and its well-developed characters. The protagonists are a strong and intelligent woman and a man with a strong moral compass."

Epic Book Society, Best Age Gap Romance Books

"Why is this book hidden away? Much more than a romance. An enjoyable, good read with many twists and turns. It's a romance which could seem doomed, but also covers many contemporary themes while bringing the music business and a small town to life."
