Hannah Kent: On Burial Rites, her first novel, and the imposter phenomenon
Beautifully written, it reeks of authenticity. You get a real sense of how harsh and arbitrary life must have been in Iceland nearly 200 years ago. I agree with the attached review, though - the novel really sings when it's written in the voice of Agnes. The constant shift in person can be distracting.
