EMPIRE OF IVORY
This is the fourth book in Novik's excellent series about the dragon Temeraire and his rider, Laurence. As usual, their adventures are compelling, and series fans will be on the edge of their seats. Ending with a tense and dire cliff-hanger, this story will leave readers clamoring for more.
However, things are looking grim for England's dragons, so Temeraire, Laurence and a cadre of ailing dragons are dispatched to Africa, where they hope to find a cure for the mysterious and deadly disease. (Del Rey, Oct., 400 pp., $7.99)
