Book of Forbidden Words: A Novel

From bestselling author Louise Fein comes a new historical novel about an encrypted manuscript that unleashes a chain of consequences across 400 years, set in a world of banned books, fear of new ideas, and the dangers of censorship, perfect for fans of The Briar Club and Weyward.

""What power lay there in words on a page. And with that thought, Charlotte knew she would not rest until she had seen what was in the manuscript that Lysbette so desperately wanted to preserve in print.”

1552, Paris: Against a backdrop of turmoil, suspicion, and paranoia, the printing press is quickly spreading new ideas across Europe, threatening the power of church and state and unleashing a wave of book burning and heretic hunting. When frightened ex-nun Lysbette Angiers arrives one day at Charlotte Guillard’s famous printing shop with her manuscript, neither woman knows just how far the powerful elite will go to prevent the spread of Lysbette’s audacious ideas.

1952, New York: Milly Bennett, lonely and unmoored, is a seemingly ordinary housewife with a secretive past. Balancing the day-to-day boredom of keeping house and struggling to find her way with the mothers at her children’s school, she finds her life taking an unexpected turn as conspiracies spread amidst the paranoid clamors of McCarthy’s America. When a relic from her past presents her with a 400-year-old manuscript to decipher, she is reluctantly pulled into a vortex of danger that threatens to shatter her world.

From the risky backstreets of sixteenth-century Paris to the unpredictable suburbs of mid-twentieth century New York, the stakes couldn’t be higher when, 400 years apart, Milly, Lysbette, and Charlotte each face a reality where the spread of ideas are feared and every effort is made to suppress them.

Dramatic and affecting, and inspired by the real-life encrypted Voynich manuscript, Book of Forbidden Words is both an engrossing story about a timeless struggle that echoes through the ages and a testament to the indomitable spirit of those who dare to let their words be heard.
