Elemental Magic (Reader/OC x Bucky Barnes) Book One

You are the oldest Maximoff who escapes Sokovia with your elemental magic. You hold a grudge against Tony Stark, but call him in to get your triplet brother and sister out of Sokovia, as they have the powers of speed and chaos magic. Your powers are somehow connected to Natasha and her experiences in the Red Room, and the secret identity no one knows about.

Note: This book sets up the story for books two and three, so this should be the shortest, as it simply adds context.

Book One in the Elemental Magic Trilogy.
