Levi's latest novel, Septimania, to be released in April, 2016 by Overlook Press, follows a shy young organ tuner who falls in love with a mysterious math genius, Louiza, only to find she has disappeared. While trying to find her, he discovers he is the heir to the Kingdom of Septimania, given by Charlemagne to the Jews in the 8th century. Over the next 50 years, Malory’s search for Louiza leads to encounters with Aldo Moro, Pope John Paul II, a band of lost Romanians, a magical Bernini statue, Haroun Al-Rashid of Arabian Nights fame and an elephant that changes color, a shadowy U.S. spy agency and one of the 9/11 hijackers, an appleseed from the original Tree of Knowledge and the secret history of Isaac Newton and his discovery of a Grand Unified Theory that explains everything. But most of all, Septimania is the quest of a Candide for love and knowledge, and the ultimate discovery that they may be unified after all. Jen Baker at Booklist gave Septimania a starred review, calling it "a literary dream of a book" and "a storyteller's work of magic, and a fantastically suspenseful adventure" and compares it to Michael Chabon and Jonathan Franzen. Kirkus Reviews calls Septimania a "thoroughly intellectual postmodern fable, wise yet melancholy, meant to be read slowly and savored." In a recent Publisher's Weekly review, Septimania was described as "highly intelligent, insanely ambitious, and restlessly imaginative."
