A Braintree second grader is so devoted to her little brother she wrote him a book. Marin and Henry share a special bond and at eight years old, she is already looking out for him.

“She loves her brother, and it’s been hard for her,” their father Ross MacDonald said.

Henry is two years old and was recently diagnosed with autism. Soon after, Marin decided to create something to bring him joy and comfort.

“Instead of like carrying around a stuffed animal or a blanket around or like a lovie, he carries this book around,” Marin said.

Their mom, Alison, says Marin came up with the idea to make a book for Henry and wrote it about his favorite thing: dinosaurs.

“She brought it over to her brother and said ‘I have a surprise Henry, I wrote a book for you.’ And she had about maybe eight drawings of dinosaurs that she had come up with,” Alison MacDonald said.
