How would you interpret ‘heart interest’ here?
“Vassals of Majesty” by local wordsmith Harrison Shepherd proves nothing short of sheer fascination. It might seem only stuffed shirts and long-haired professors would clamor to read of men living hundreds of years ago. Not so! Every heart will pound as conqueror Cortez pitches battle against his foe. This book has it all: blood-curdling treachery, and even heart interest. The female pulse will race for handsome Indian prince Cuautla. With the speed of a locomotive the story hurtles to its epic conclusion. Mrs. Jack Cates, owner of Cates Bookshop, confirms she cannot keep it on the shelves.
How would you interpret ‘heart interest’ in the sentence: This book has it all: blood-curdling treachery, and even heart interest?
Thanks!
