The paradise problem

Anna Green has a plan. Marry Liam 'West' Weston at the start of college to get the family discount on campus housing and then sign the divorce papers as the graduation bells chime. Everyone's happy and they can both go on their merry ways : Anna to live as a starving artist and West to teach at Stanford. A seemingly straightforward plan until West presents Anna with a catch - a big catch. West is one of four heirs to the Weston Foods conglomerate and although he wants little to do with his family's heartless institution, he does want the one hundred million dollars he's set to inherit - however, he won't see a penny until he's married.
Five years post-grad Anna must escort West to his sister's lavish wedding, present herself as his devoted wife and be convincing enough that West gets his inheritance. The only problem, Anna is feisty, foul-mouthed, messy, and the complete opposite of what the Weston family had anticipated for their son. Will they be able to convince everyone of their heartfelt marriage or will it all come crumbling down ?
