According to Variety, the novel is "an epic adventure about orphans raised in Britain's Coram hospice in 1741." Sounds a bit like an Oliver-like tale, doesn't it? However, it's a little more than that -- think Oliver! meets Christopher Pike or R.L. Stine. On the Egmont website for the book, the description starts off with: "Otis takes babies and money off desperate mothers, promising to deliver them to the Coram Foundling Hospital in London. Instead, he murders them and buries them by the roadside, to the helpless horror of his mentally ill son, Mish." Nice, eh? The description goes on to talk about families and babies, so I'm not quite sure how the hospice fits in to it all.
If you're curious, there's already a theater adaptation of the book, which you might have heard of. After a successful turn at London's National Theater, the adaptation is set to open this May in New York. However, this is a completely separate production.
