Animal heart

the long version

"When an eerie mass stranding of whales and dolphins takes place along the mist-shrouded Oregon Coast, forensic wildlife pathologist Isabel Spinner and her friend and co-worker Marian Windhorse Gray covertly investigate this disaster as a crime against wildlife. For years, Isabel has kept some emotional distance between herself and other humans, while devoting herself to easing the suffering of animals. But when Isabel finally connects with Marshall McGreggor, an undersea photographer whose recent transplant has him delving into the mystery surrounding his new heart, the two find themselves making surprising decisions that will forever change their lives." "Based on cutting-edge science, this book tackles such timely and troubling issues as low-frequency active sonar and animal experimentation and forewarns of a future of Dead Zone oceans, disappearing species, and a world with creatures whose DNA boundaries have been genetically blurred."--Jacket.
