Sweet Revenge ...
Having survived a near-catastrophic incident, wealthy widow Laura and her younger partner, songwriter Ali, finally manage to settle down amongst their tight community of friends in rural England. But they're completely unaware that the 'incident' was no accident - and the perpetrator, stepdaughter Stephanie, isn't finished yet and will stop at nothing to destroy them both.
Laura, widow of Ireland's most successful racehorse breeder, Frank O'Brien, sets about sharing her fortune in a philanthropic way. She's also able to back Ali, who's finally realising success as a songwriter and producer; his band Coolstar is now getting streamed big-time. After months of turmoil, at last, life seems good.
Stephanie has detested her stepmother Laura since the day she met the bitch and has been obsessed with getting rid of her. Now she has a new scheme - a glorious celebration of her forensic planning. It's a dead cert.

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.
“Oh my goodness, it's a tour de force, it's huge ... and it's great!!🎶 👍 🎵 👍” P.D.
“I tried a musical novel hybrid with my own #Zero, which I spotted in a charity shop today & note has (checks stats) 1 monthly listener on Spotify. Better luck to the talented @gethynjonesuk with his bold take on an underpopulated genre. Check it (Fatal Equation) out.” Neil McCormick, Daily Telegraph.
“An intertwining tale of a love that doesn't conform to society's self-limiting rules, shot through with a fine understanding of the often unspoken side of life's relationships. 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
“I absolutely love this book. It has everything you could possibly wish for ... can't wait for the next one! Thank you Gethyn Jones.” D.H.
“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.” Pam

“The music is amazing - you don't know what to expect next! Do Coolstar actually exist? paulmonomixboy
“I could certainly get used to living the lifestyle of the super rich, but dealing with the fallout from contentious bequests and grasping beneficiaries, I don't know whether they'll all make it out alive! Highly recommended as an enjoyable, absorbing read. ” S Archibald

“This book is a lovely story incorporating many different facets of life. It shows the wonderful characteristics of some people and the truly appalling characteristics of others. In the end goodness prevails but there are many tangled threads along the way. And I love the accompanying music.” Janiemac
