Kate Kerrigan, who also writes as Morag Prunty, was in a taxi travelling from Heuston Station when she left her laptop behind on Tuesday afternoon just after 1pm.
The author said she was "in bits" about the loss.
After hearing about the devastating loss, Ahern quickly took to Twitter hoping her legions of followers could help to track down both the taxi and the laptop.
Kerrigan herself was even given access to CCTV in the hope of being able to see the taxi's registration number.
Within a couple of hours both authors had been inundated with messages of support.
Cecelia returned to Twitter to thank her followers and those who had helped spread news of the loss, however, the laptop has still not been recovered.
Daughter of the former Taoiseach Bertie, Cecelia has enjoyed success as an author since her first novel, 'PS I Love You' was released in 2004. It was also made into a movie starring Hilary Swank and Gerard Butler.
Ahern has since written nine other books and two collections of short stories.
