This Billionaire's Feud - This Billionaire, #39

Mike and Mallory grew up together with feuding families. Both families were successful with farming and never got along. Mallory has been away on the west coast for the past five years, but the death of her grandpa has brought her back home. Now her family needs help with dealing with her grandpa's will. Why did he leave part of his fortune to Mike's family?  Mallory contacts Mike to help her with the will, but what they find will change everything.
As Mike and Mallory fall for one another, their families try to push them a part. Will Mike and Mallory disregard their feuding families or will it tear them a part?
