The Lifeboat by Charlotte Rogan
Grace Winter just got married in London and is now returning to New York via ocean liner. It’s been two years since the Titanic disaster so it is fresh in everyone’s minds yet no one actually thinks a disaster will occur. Until it does… There is an explosion aboard the ship and the lifeboats are launched. Grace’s husband puts her on a lifeboat and she hasn’t seen him since. Now she and her fellow forty or so lifeboat passengers must survive while awaiting rescue.
This is a great psychological study. It’s fascinating to see the dynamics aboard the small vessel and the interactions between the passengers, as well as the alliances which form. Even more fascinating, and disturbing, is imagining yourself as Grace and wondering what you would do in her place.
