Amy's Sinnoh Adventure (A Pokémon D/P/PL Fan-fic)

Here we are in the land of Pokémon, and a new heroine by the name of Amy Baker is about to go on her very first Pokémon adventure in the Sinnoh region. Along with her best friend Melanie Russel, Amy's eight-year-old sister Dawn, and a brand new friend named Matt, we will watch Amy's adventure unfold. All the while she and Melanie become Pokémon coordinators and trainers, Amy tries to become the new Sinnoh League Pokémon champion, and all four of them try to ruin a criminal organization plans to create a new world and are also out to get rid of everybody else in the world.

POKéMON DOESN'T BELONG TO ME; ALL CREDIT GOES TO ITS CREATORS.

(Pretty much follows the storyline of Diamond (D), Pearl (P), and Platinum (PL) games.)
