This is an absolutely delightful series of 8 books- I believe it is now a TV series in Australia. The The books have a very homeschool-y feel to them. They make a great read aloud books for younger kids- and are good for 9-12 year olds. REALLY exceptional!
When four siblings go on holiday in The Lake District in England they create their own world and adventures over the summer. They camp out on an island with no adults! The books were written in the 1930’s but other then the fact that they look forward to tinned tongue for lunch you would never know it!
From the publisher:
The first title in Arthur Ransome’s classic series, originally published in 1930: for children, for grownups, for anyone captivated by the world of adventure and imagination. Swallows and Amazons introduces the lovable Walker family, the camp on Wild Cat Island, the able-bodied catboat Swallow, and the two intrepid Amazons, Nancy and Peggy Blackett.
