Sail by James Patterson & Howard Roughan
Katherine Dunne is a widow, a heart surgeon and mother of three spoiled
kids ages 18, 16 and 10. They were a somewhat dysfunctional family before dad died; after
he died, things got worse. So she decided she and the kids should spend the summer on the
family boat and try to become a family again
without her new husband. Her former
brother-in-law would be the captain of the boat.
