First up is the unabridged version of Silver: Return To Treasure Island :
July, 1802: In the marshy eastern reaches of the Thames lies the Hispaniola, an inn kept by Jim Hawkins and his son. Late one night, a mysterious girl named Natty arrives with a request from her father, Long John Silver. The pirate proposes that Young Jim and Natty sail to Treasure Island in search of Captain Flint's hidden bounty, left behind many years before....
Featuring a cast of noble seamen; murderous pirates; and stories of love, valor, and terrible cruelty, Silver is a worthy sequel to Treasure Island- and a work of extraordinary authenticity and imaginative power from one of England's greatest writers.
