Two weeks before her son turned 5 in April, Guirlande Olivier said, she asked what he wanted for his birthday.
Ashton Antoine’s response turned into a debut book: “5 My Magic Number.”
“He said, ‘Mommy, this is my magic number,’ ” Olivier said Wednesday. “Let’s make a book.”
The 26-page paperback book was published July 28, and now the kindergartner is on a book tour of sorts.
On Wednesday, he visited Boston City Hall, where he played violin for Mayor Martin J. Walsh and read his book in the Eagle Room.
Last month, Ashton met Boston Police Commissioner William B. Evans at a book signing and received a “Governor’s High Five Award” from Governor Charlie Baker.
During his meeting with Walsh, Ashton said his writing career is just getting started.
“I’m going to write books for everybody,” said Ashton, who attends Brooke Charter School in East Boston.
His book is a celebration of the number five and the ways it has figured into his young life.
“This year is 2016. I turned 5 years old,” Ashton writes. “In fact, my life has been full of events that include multiples of 5.”
Ashton writes that he speaks five languages, English, French, Haitian Creole, Chinese, and Spanish, and plays five instruments, violin, piano, guitar, flute, and trombone.
Olivier said the book is meant to let children know that their age shouldn’t be an obstacle. She said she taught Ashton Haitian Creole and French and got him started on violin lessons two years ago.
“His message and my message is . . . to help the kids know that they can do a lot. They can speak more than one language. They can do a lot, keep them busy,” said Olivier, a native of Haiti who works in marketing at the Edgar P. Benjamin Healthcare Center in Roxbury. “As a parent, for me the message is if you support your kids they’ll do things that you don’t think they can.”
Olivier, who lives in Randolph, said she helped her son in writing the book. It was published by a division of JEBCA Ministries Inc., a faith-based educational, cultural, and charitable organization serving the Haitian community.
Olivier said she is trying to raise money through a GoFundMe page to translate the book into other languages. Proceeds from the book sales, she said, will go toward giving the books away to charities.
For his meeting with Walsh, Ashton wore a gray suit, blue shirt, and tie. He wore two pins on his suit jacket, one of the American flag and the other of the City of Boston seal.
Ashton said he dreams one day of wearing a badge: “To be a police officer and a commissioner.”
Walsh said he was impressed with his young visitor, who autographed a copy of his book for the mayor.
“His penmanship is even nice,” Walsh said.
