This gorgeously illustrated pop-up book takes readers deep beneath the water’s surface where they are greeted with a symphony of new sounds. This aquatic adventure features a humpback whale that communicates with noisy roars and sighs and whose “songs” carry for hundreds of miles underwater. Children also discover the playful chattering of dolphins, the boisterous honking of seals, and much more. Maurice Pledger’s cunningly engineered pop-ups create an unforgettable 3-D seascape.
