Imported from the UK! Summoned to a planet-wide library known only as The Library, the Doctor and Donna discover an archeological expedition led by the mysterious Dr. River Song. Curiously, while the Doctor had never met Song, she was quite familiar with him; she even carries the Doctor's sonic screwdriver, heavily modified with additional features! The Doctor Who: Future Sonic Screwdriver recreates River Song's sonic screwdriver from "Silence in the Library" as a 7" long replica that includes light and sound effects, plus blue and red interchangeable LED ends.
