The Picts & the Martyrs: Not Welcome at All — Arthur Ransome

As the classic series continues, an unexpected visitor forces a group of children to go to great lengths to enjoy a summer of fun and adventure.
 
The Amazons' mother (doubtless suffering from exhaustion) has gone off sailing in the North Sea with Captain Flint on a rest cure, but she has allowed her two daughters to stay on the lakeshore with their trusty cook. She's also permitted their two old friends, Dick and Dorothea Callum, to come up for a visit. But when the redoubtable Great Aunt hears of their abandonment, she's horrified and off on the next train.
 
The Amazons are dismayed; not only will their solo holiday be ruined, but now they'll also have to hide their two guests in the woods in an abandoned shepherd's cottage (where they'll be forced to live off the land like the ancient Celtic, “Picts”) while the Blackett sisters will be required to dress up in white pinafores, practice the piano, and recite reams of poetry aloud (therefore “The Martyrs”).
 
Friendship and resourcefulness, dangers and excitement: Arthur Ransome's Swallows and Amazons series has stood the test of time. More than just great stories, each one celebrates independence and initiative with a colorful, large cast of characters. The Picts & the Martyrs (originally published in 1943) is the eleventh title in the Swallows and Amazons series, books for children or grownups, anyone captivated by a world of adventure, exploration, and imagination.
