Renowned English primatologist Emily Bennett carries purpose in the palm of her hand, whereas pretty boy defense lawyer Will Thomas drags it like a scrap of toilet paper stuck to his shoe. The chimpanzee communication project known as Simian Says, founded by Emily, has taught sign language to generations of chimps. Now, by adopting ASL recognition and speech synthesis technology designed for communication-impaired humans, her project has given voice to a particularly charismatic chimp named Sparks. When Emily is arrested for the rescue of three experimental chimps from a Seattle lab, the stage is set for her prize pupil to testify. Will the aimless young lawyer's attraction to his ambitious client drive him to win her case or interfere with her scheme? In the most sensational trial of the twenty-first century comes the most anticipated witness in courtroom history. The prospect of meaningful communication with a great ape is just around the corner-not the ambiguous interpretation of body language and gestures, but plain English. What will they say? What would you ask? What does it change? Available in paperback or digital at Amazon and other online booksellers. "Waterfall Dance is an intricate balance of politics, romance, science, and courtroom drama. A deeply enjoyable read which gently unveils the main character's humanity." Steven Nyquist
