A wild heart beats within New York City. Amid concrete and skyscrapers, the Wildlife Conservation Society works to preserve and protect the animal kingdom both within and beyond the borders of the five boroughs. But dangerous creatures don't always have claws and fangs, as Assistant DA Alexandra Cooper and NYPD detectives Mike Chapman and Mercer Wallace know all too well. Predators lurk close to home, and in the aftermath of the shocking assassination of an iconic public figure --- someone Alex has worked with for years --- the trio must unravel the motive behind the shooting to discover who is the bigger snake: the killer or the victim.
