Burning Bright derives its title from the opening phrase of William Blake's great poem: "Tyger, tyger, burning bright/ In the forests of the night. . . . " When one learns that this novel's author is Tracy Chevalier, it follows as the night the day that we will enter the world of Blake's London and find "fearful symmetry" there. If not precisely formulaic, Chevalier has by now established a formula for her process and success: Take a historical period with a recognized figure or work of art, add some invented families and an engaging young person or two, do the research with specificity, and invite the reader in. Chevalier made her reputation with Girl With a Pearl Earring, the bestselling evocation of an artist's model, Griet, a 16-year-old servant in the house of Johannes Vermeer.
