Inescapable
The attraction was instant, immediate, too inescapable for either to resist.
Inexplicable
Delilah was a stripper, trying to make a better life for herself. Edward was a professor from old money trying to save his nephew from a femme fatale. They had nothing in common, no reason to come together, no reason to love one another.
Irrepressible
No matter how Delilah tried to deny her feelings for Edward, he would not allow her to run away from what they both couldn't deny. As passion crackled and flamed between them, Delilah found herself swept away by Edward with a ferocity that would not be denied.
Irresistible
Sometimes love will not be denied. Sometime passion will not be tamed. Two forces come together and cannot break apart.
