The Portal and the Panther (Guardians of the Portal) (Volume 1)

The only thing seventeen year-old Jon Parker wants is to escape his sleepy hometown of Mecksville, Arkansas. But everything changes when Jon stumbles into the boys’ bathroom and transforms into a black panther. Without choice, Jon is thrust into a world where parallel universes are real, shapeshifters exist, and dangerous “intruders” can control the elements with a mere thought. Jon learns he’s inherited his shapeshifting ability from his long-dead mother, and now, like it or not, his mission is to protect our world from invaders from other worlds. But is it a mission Jon will accept? His decision will impact the people he loves -- and our whole world.
