The world has no shortage of moral ambiguity, especially in the emergency room. In Pulse, Dr. Jackson is an emergency room physician who seems to have the big house, beautiful wife, and an impeccable reputation as one of the most respected emergency physicians in Dallas. As the layers get peeled back, Dr. Jackson's life isn't so perfect after all. Filled with unique twists, complex medical cases, personal issues, and even a chess game, Pulse proves that there is always more to the story!

Long before the Queen's Gambit was a popular show, author Judy G. Walters was writitng chess into the backdrop of this medical thriller. Pulse is the first book in the Vital Signs Series. Each book in the series gives a behind-the-scenes look at emergency medicine, thrusting the listener right into the action, all while featuring the back story of a specific character. All Vital Signs series books are wrapped neatly around a game of chess. Even if you've never played chess before, this unique approach will be entertaining nonetheless!
