That is the signal. The magic tree house is back.<\/p>\n<p>Teddy and Kathleen are waiting inside with a job from Morgan. Merlin is unwell and unhappy, and Jack and Annie are collecting secrets of happiness to take to him. They have two. This trip is for the third.<\/p>\n<p>They land in a misty tree above a beach and go swimming, which is very much Annie&#8217;s idea of a mission. Then a tall ship appears out of the haze.<\/p>\n<p>Not pirates this time. The name on the side is HMS Challenger, and it turns out to be the first ship in the world sent out purely to do science.<\/p>\n<p>The best company in the book is a man called Henry, who comes ashore with a butterfly net and a bow tie and introduces himself by saying he has found a rare creature called a Jack-and-Annie. He shows them his laboratory. Bottles of sea slugs, a sea horse the size of a grain of sugar, plates of ocean mud he cheerfully calls ooze.<\/p>\n<p>He also shows them a nautilus shell he refuses to call a specimen, because he was fond of the creature that lived in it and wishes he had put it back in the sea. That small sad moment is doing quiet work in a book about happiness.<\/p>\n<p>A heads up about the middle. A storm hits while the children are on deck, and both of them end up in the water. Jack&#8217;s life vest is washed off him, he is pushed under, and there is a page where he is out of air and cannot get back to the surface. Annie has disappeared. It is written to be frightening and it succeeds.<\/p>\n<p>They are not left there long and a rescue arrives quickly. Still, if your reader is nervous about deep water or has ever had a fright in the sea, that stretch will stay with them, so it is one to read nearby rather than at lights out.<\/p>\n<p>Jack carries a magic wand and there are three rules about using it, and the rules are half the fun. Try your hardest first. Five words only. Never just for yourselves.<\/p>\n<p>If the sea is the pull here, Dolphins at Daybreak sends the same pair down to a coral reef in a tiny submarine, with a shark somewhere below them.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mary Pope Osborne&#8217;s Dark Day in the Deep Sea is a sea adventure for 7 year olds about two children who join a Victorian ship hunting for a monster.
