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.

The first day out, the daughter (18) tries to commit suicide and Jake (the captain) finds a ruptured hose as the boat fills with water. It’s all goes downhill from there…really fast.

The sinister characters, surprises and subplots add up to a quick, fun read. A little sex and a big snake are thrown in for good measure.
