During the first third of the book, I thought I was reading a re-telling of The Secret Garden but little hints were being dropped along the way that this was something more than a young person being taken into a rich family’s home to help their child with an affliction. It’s sorta of a cross of what you get if you were to combine The Secret Garden with Misery and add/subtract a few things. At times it makes you wonder if you were reading a suspense, horror, or thriller. Very high on the psychological thrill component. It continues to build and build by way of the relationships formed between the main protagonist and the supporting characters. Although somewhat predictable in some places, there were nice surprises in other places. Very high on the can’t put down factor.
