Harper Reid's summer is not off to a great start. After the death of her grandpa, she moves across the country, leaving her friends and Dungeons & Dragons group behind. Finding herself back on the farm where she spent her childhood is not how she planned on spending her senior year, but running into Ollie Shifflet, her childhood best friend and first crush, makes things a little better. When Harper discovers Ollie and her friends are starting a new D&D campaign, she quickly joins the group, and as Harper and Ollie reconnect in the real world, romantic tension begins to build between Harper's brash Barbarian and Ollie's proud Paladin.

With each gaming session, the two friends start to question if maybe there is something more between them, until their D&D characters' relationship complicates Ollie's goal to keep her bisexuality private and Harper's struggle to stay true to herself and her goals for the future. As the school year starts to come to a close and the campaign's final boss looms on the horizon, Harper and Ollie must decide if their feelings for each other are more than just a fantasy and if they are ready to make them a reality.
