A maritime archaeologist raises a medieval monastery span from the mud of the River Shannon, sunken for 1,200 years... and finds it perfectly preserved.

What could account for this astounding longevity? Why are his colleagues and the Church so desperate to prevent him learning the secret? And why is his consummate lover his greatest enemy?

Griffin Clonmac will go through hell to find out.

He won’t go alone. Inspired by a real discovery, Clonmac’s Bridge shifts between contemporary times and 9th century Ireland. It tells the story of two men who struggle against envy and mediocrity — a millennium apart — aided only by a loyal helpmate and an unconquerable will.

An archaeological thriller, a love story, and a pensée on society then and now, Jeffrey Perren fans are sure to find this latest novel his best yet.
