Infinite Movie Worlds: Traveling Through an App

A mysterious mobile app grants Jake Mitchell the power to enter movie worlds. He encounters a charming princess in The Princess Diaries, obtains the genius drug NZT-48 in Limitless, and acquires invisibility potions in The Invisible Sisters. But this is just the lowest level of access to these cinematic universes; beyond lie even greater possibilities: Iron Man's technology, Underworld's supernatural powers, X-Men's mutations, Transformers' alien tech... Jake's goal is to master them all and unlock every world the app has to offer. — Description from novelcodex.org
