The Unforgotten Vow (Paperback) (ISBN-13: 9798988122586)

"Patroclus, my mate of more than a century, has always been the steady flame to my wildfire. But I can't shake the feeling of restlessness that has plagued me for the past twenty-two years of our bond. Despite Patroclus' unwavering love and support, I feel like something is wrong, like a link in our chain is missing."

Achilles, Greece's most beloved warrior and Flame has already suffered tremendous loss during his Immortal life.

Losing his twin sister and Viking Commune to Ares' and his army of Shifters, Achilles found a new home in Greece.

Making a name and a life for himself at Delphi, Achilles found something other Immortals only dream of, his Fated Mate, Patroclus.

After a century of happiness, Achilles can't stop the unshakable feeling that something is missing from their lives and whatever it is, is desperate for their help.
