"Insecure college senior Orion loves music, books, and his best friend Niko. When the two of them find a secret basement in their rambling old off-campus house, at first Orion's thrilled. It's another secret to share, an adventure to maybe, at last, bring them closer together. But something's wrong: the basement doesn't end. Blandly decorated halls stretch on for miles past peeling wallpaper, empty bedrooms, and countless stairwells always leading down. Soon they realize Downstairs is a snarled tangle of possibilities. Something down there multiplies everything: architecture, emotions, even people. Together they must navigate an increasingly dangerous labyrinth filled with two-faced doppelgangers, treacherous architecture, and long-buried secrets. Most dangerous of all is Orion's consuming obsession: somewhere down there, is there a Niko who loves him back?"--Amazon.ca.
