E Nesbit
Three children discover an old country estate during their school holidays. When they're exploring it they come upon a mysterious young girl claiming to be a fairy princess. She shows them the castle's treasure, including a ring that will turn you invisible. But no one is more surprised than she when she slips it on her finger ... and disappears! The ring is indeed magical, and the children waste no time finding out what else it can do.
Lovers of classic children's literature will delight in The Story of the Treasure Seekers from noted British author E. Nesbit. This engaging tale about the plucky Bastable clan and their plan to improve their family's financial fortunes influenced many twentieth-century juvenile fiction writers, including C.S. Lewis.
When their father is taken away by strangers, the lives of three children are altered forever. They move with their mother to a cottage by a railway. The railway becomes their playground, and they befriend the rail workers and passengers who eventually help to reunite them with their father.
