Lost for three or four years, eh? Mmmkay, well....I'd say it is possible to find it as Mercury is about to conjoin you, the Moon is in mutual reception with Mercury and Saturn, the ruler of the 2nd is retrograde.
As for the place, well, the Moon is combust and about to square Mars. Since the Sun rules the 9th and Mars is in the 9th, it could be in some book, school book or religious book or library book. Good amount of air signs show it would be on a shelf or high up. As Mercury and Jupiter are in earth signs, this may show a lower floor room, basement, cellar or place where library books or religious books/items are stored.
You may have moved these boxes of books recently with that new moon recently occuring or they may have been recently damaged or uncovered/discovered.
hope that helps.
