My daughter who is four is a big fan of the Octonauts books and TV series and lets be honest so am I. These new books by Simon and Schuster are stories based on episodes of the TV series so not totally original like the books by Meomi. The Meomi books are beutifully illustrated, funny and well written. These TV spin off books are not as well illustrated lack humour and are shorter in length. There are facts about the creature at the end of the story which is a nice touch. My daughter still enjoyed the story but I just feel the magic has left the books and its more of a cash in on a successful idea. My view would be buy the Meomi books and watch the TV series.
