A talented Yale graduate set to pursue her dream as a writer in New York died in a car crash near her Massachusetts home.

Marina Keegan, 22, was going to move into a Williamsburg apartment with four friends this week and begin her job as an editorial assistant at The New Yorker.

“I just can’t believe she’s gone,” said her devastated mom, Tracy Keegan, who just a week earlier saw her daughter graduate.

“She truly could not have been more excited and happy about getting to embrace the world beyond her college education, and it’s nothing less than a crime that she’s not being given that opportunity.

“She was nothing less than amazing,” she told The Post. “I honestly feel she was a gift given to all of us.”

Keegan died Saturday afternoon while she was a passenger in a 1997 Lexus driven by her boyfriend, Michael Gocksch. He hit a guardrail near Cape Cod, and the car rolled over at least twice, the Boston Globe reported.

Keegan, who lived in Wayland, died at the scene. Gocksch, 22, who lives on Long Island and also just graduated Yale, was hospitalized in stable condition.

Both victims were wearing seat belts, and speed did not appear to be a factor, cops said.

Besides a passion for journalism, Keegan, who wrote for the Yale Daily News, was also a talented playwright, whose show, “Independents,” is set to be staged at the New York Fringe Festival this August.

“She was a fantastic writer, just a wonderful human being who touched the lives of everyone she met,” her dad, Kevin Keegan, said.

Mark Sonnenblick, who also had just graduated from Yale, was one Keegan’s collaborators on the production.

“She wrote the script and was very much the driving force behind the characters and the story,” he said.

Her mom said, “I believe my daughter was like a comet. She burned so bright, so strong, for just a short moment on this planet. Honestly, we are all worse because she’s no longer here.

“I really felt blessed she was part of my life.”

Keegan, who had an older and younger brother, was president of the College Democrats and had organized Occupy Wall Street protests on campus.

She wrote for the school paper about the large number of graduates who went on to work in finance.

“She told me she was the most proud of that article,” her mom recalled.

A woman who answered the phone at Gocksch’s Centerport home was too distraught to talk.
