 Although the title rather suggests a sequel to The Blue Lagoon, this is rather a variation on the same theme- neither Christopher Atkins nor Brooke Shields returns - Emmeline is dead, but a new generation is shipwrecked again on a desert island. This time the two kids, Richard and Lilly, have no experience in the civilizes world at all, and have to discover everything on their own, but loves proves an indomitable instinct, even given a  choice  of one inhabitant per gender.
