From the New York Times bestselling author of The Map of Time and The Map of the Sky , the final installment in the award-winning trilogy that The Washington Post called “a big, genre-bending delight.” When the person he loves most dies in tragic circumstances, the mysterious protagonist of The Map of Chaos does all he can to speak to her one last time. A session with a renowned medium seems to offer the only solution, but the experience unleashes terrible forces that bring the world to the brink of disaster. Salvation can only be found in The Map of Chaos , an obscure, hand-written mathematical treatise that he is desperate to uncover. In his search, he is given invaluable help by Sir Arthur Conan Doyle, Lewis Carroll, and of course by H.G. Wells, whose Invisible Man seems to have escaped from the pages of his famous novel to sow terror among mankind. They alone can discover the means to save the world and to find the path that will reunite the lovers separated by death. Proving once again that he is “a master of ingenious plotting” ( Kirkus Reviews ), Félix J. Palma brings together a cast of real and imagined literary characters in Victorian London, when spiritualism is at its height. The Map of Chaos is a spellbinding adventure that mixes impossible loves, nonstop action, real ghosts, and fake mediums, all while paying homage to the giants of science fiction.
