Purchase ‘Roswell: Shades
Publisher: Simon & Schuster Trade
Pub. Date: August 2002
Now that their best chance for returning to the home planet has left without them, the “Czechoslovakian” residents of Roswell (code for aliens) must adjust to a more permanent existence on earth than they were expecting. Burdened with new responsibilities — and new threats — the alients and their human friends deal with the typical trials of growing up: troubled relationships, parental issues, and feeling like you’re from another planet.In Shades, Roswell residents are threatened by ghosts from their pasts, and wise man River Dog points to an otherworldly culprit.
