Many authors dream that one day their book signings will draw huge crowds. That dream recently came true for one 7-year-old writer.
Evan Moss, who suffers from epilepsy, needs a service dog to help alert him and his family when he is about to have a seizure.
The specially trained dog will cost the family more than $13,000. Acting on his sister's suggestion, Evan decided to sell his book to raise funds to help pay for the dog.
In the 26-page book, titled My Seizure Dog, the 7-year-old wrote about what a service dog would be like and how it would help him.
"The seizure dog will eat pizza with me," Evan writes. "If I ever go to outer space the seizure dog will come too."
"The dog will also hopefully give him a little bit of independence from that as well," the child's father, Rob Moss, said.
The line stretched out the store's door at Evan's recent book signing. Hundreds of people showed up to show their support for the boy and his cause.
His parents say they're overwhelmed by the support they have received.
"There's a lot of people here we know, but the majority of the people in this line we've never met," Evan's mother said.
So far, the family has raised about $4,000.
