We Didn't Mean to Go to Sea is the seventh installment in Arthur Ransome's classic Swallows and Amazons series. The book sees the four Walker children (the Swallows) temporarily separated from their mother and sailing master, when a sudden fog causes their hired dinghy, Goblin, to drift out into the North Sea, carrying them toward the open ocean. The story becomes a thrilling narrative of self-reliance, with the children having to use all their sailing knowledge and courage to navigate the hostile waters and make landfall in Holland. The book is a celebration of competence, seamanship, and adventure against the backdrop of real danger.
