'Absolutely brilliant. Ellen Lark is unforgettable' Emilia Hart, author of Weyward 'Vivid. Eloquent. Offers insight as well as delight' Guardian

Ellen Lark is on the verge of marriage when she and her fiance receive an unexpected visit from Alexander Graham Bell.

Ellen knows immediately what Bell really wants from her. Ellen is deaf, and for a time was Bell's student in a technique called Visible Speech. As he instructed her in speaking, Bell also confided in her about his dream of producing a device which would transmit the human voice along a wire: the telephone. Now, on the cusp of wealth and renown, Bell wants Ellen to speak up in support of his claim to the patent to the telephone, which is being challenged by rivals.

But Ellen has a different story to tell: that of how Bell betrayed her, and other deaf pupils, in pursuit of ambition and personal gain, and cut Ellen off from a community in which she had come to feel truly at home. It is a story no one around Ellen seems to want to hear - but there may never be a more important time for her to tell it.
