The highly anticipated The Book of Life  concludes Deborah Harkness’ All Souls Trilogy. In the final volume, Harkness deepens her themes of power and passion, family and caring, past deeds and their present consequences. In ancestral homes and university laboratories, using ancient knowledge and modern science, from the hills of the Auvergne to the palaces of Venice and beyond, witch Diana Bishop and vampire scientist Matthew Clairmont at last learn what the witches discovered so many centuries ago.
