The Saltwater Ponygirl: On a tiny island called Chincoteague, Big dreams are about to come true...For a girl named Minnow, and her pony Marshy

Since Minnow’s first word was pony, she’s dreamed of riding in the Pony Swim. There’s just one little tiny catch - girls aren’t permitted. It’s tradition.
But that hasn’t deterred Minnow from trying every summer. And this summer, she is determined it will be the summer she makes her dream come true.
She’s got a new plan, and with the help of her best friend Matt, a Saltwater Ponyboy, she’s certain they can pull it off. With the aid of her self-centered, pirate little sister Windy, can Minnow keep her parents and big sister Summer, as well as the rest of Chincoteague from finding out her secret until Pony Swim Week is over?
What happens along the way is a series of unexpected twists, silly winding turns, and heartwarming lessons.
But through it all, there are two certainties that Minnow knows in her heart unwaveringly.
She belongs here. She’s a Saltwater Ponygirl.
And love is stronger than anything else.
