His Hawaiian Heart by Maggie Ryan

Is a shared name fate or coincidence?

Entomologist Sam Laughlin arrived in Hawaii looking to change the world with her research, her dream project. Insects have driven her passion for years, not love, and the honeymoon island isn’t going to change that.
When cattle rancher Samual Blackwell arrived at the Liehue airport, he was looking for his grandmother, not an auburn haired beauty in distress. He never would have believed a chance encounter at the luggage carousel would make him question everything.

Instant sparks set their love ablaze, but will his unwillingness to trust cool the fire down? If she can’t prove that she loves him and not his wealth, his fears will destroy it all.
