Set in Stone — Linda Newbery

When Samuel Godwin, a young and naive art tutor, accepts a job with the Farrow family at their majestic home, little does he expect to come across a place containing such secrets and lies. His two tutees are as different as can be--younger sister Marianne, full of flightiness and nervous imagination, and Juliana, sensible and controlled. Helped by their governess, Charlotte Agnew, Samuel begins to uncover slowly why Marianne is so emotionally fragile, and in doing so uncovers a web of intrigue. But his discoveries lead to revenge and betrayal--and lives all around are turned upside down.

Linda Newbery has written a novel in diary style, combining different voices and a different century with her usual brilliance and ease. These are characters full of the same passions as our own today, while living in an unfamiliar and fascinating time.
