Delighted, at last, to read another book by Ken Grimwood, author of one of my favorite novels “ Replay.” “Into the Deep” is similar to “Day of the Dolphin” in that it depicts scientists attempting to communicate with dolphins. Grimwood’s novel, however, takes on a more fanciful and optimist view of dolphin intelligence. As the story unfolds, the reader becomes more concerned with the mankind’s treatment of dolphins and increasingly aware of the environment we both share. “Into the Deep” is thoughtfully life affirming and wonderfully empathetic, an enjoyable read.
