28 Summers by Elin Hilderbrand

When Mallory Blessing's son, Link, receives her deathbed instructions to call a number on a slip of paper in a desk drawer, he certainly does not expect Jake McCloud to answer.  It's the late spring of 2020, and Jake's wife, Ursula de Gournsey, is the front-runner in the upcoming presidential election.  Inspired by the film Same Time.
