Glorious five. Five on Treasure Island

Five on Treasure Island is the first book in the Glorious Five series.

Three cousins - Julian, Dick and Ann - came to Georgie, a girl with a wayward character, who looks like a boy in everything. At first, the landlady, who never had friends, wanted to get rid of the uninvited relatives as soon as possible, but soon the children became friends. And when the cousins also found out that George has his own island with the ruins of an old castle, a sunken ship and a wonderful dog Timmy, they all plunged headlong into exciting adventures, turning into treasure hunters.
