Prologue of Tsuruya-ke no Okite/The Law of the Tsuruya Family

From Yen Press:  
When Haruhi Suzumiya introduces herself to Kyon by asking if he's an alien, time traveler, or psychic, he knows his chances for a normal high school experience are ruined. Bold Haruhi takes a shine to him, and uses the force of her irrepressible personality to draft him into her club to find paranormal beings. Kyon soon discovers what she's looking for: Haruhi herself has the power to destroy and create entire universes at her whim. But if she knew about her ability, it could spell disaster for everyone.
