Hooked By a Hero by Merry Farmer

The only thing more exciting than finding adventure and love on the high seas is the mystery of who Caspian really is….
When Dr. Elias Pettigrew is forced to leave England for Australia at a moment’s notice to avoid being trapped into marriage with an odious woman he could never love, he has no idea what will become of his life. Australia needs doctors, so he is certain he will find employment, but is it worth giving up his entire life, his friends, and his fortune for?
The answer to that is a resounding “yes” when he meets the beautiful and enigmatic Caspian. But a mystery surrounds Caspian that Elias cannot figure out.

Caspian certainly did not expect to find his soulmate on a sea voyage back to his ancestral home, nor did he expect for the love of his life to be an Englishman. But as soon as they meet, Caspian feels their sizzling connection. But how does he explain to Elias who he is?
