Love, Rosie, the film based on Cecelia Ahern's second book, is not loved by fans after it flopped in Ireland and the UK on its opening weekend.
The big screen adaptation of Ahern's novel Where Rainbows End was at number eight in the chart after taking in only €47,729 at the Irish box office on its first three days.
Love, Rosie, which debuted at No9 in the UK, grossed €615,7000 on its first weekend in Irish and British cinemas.
The figures are in stark contrast to the success of the film adaptation of Ahern's first novel, PS I Love You.
The movie, starring Gerard Butler and Hilary Swank, was released in late 2007 and took €2.27m at British cinemas and €125.1m worldwide.
Love, Rosie stars Lily Collins, the daughter of musician Phil Collins, and Sam Claflin who play two life-long friends whose romance is thwarted after Collins' character becomes pregnant following a drunken one night stand with another man.
The movie has a 15 certificate which puts it out of reach of young teens.
Critics haven't been too impressed, with the film receiving a rating of only 33pc on Rotten Tomatoes - a review aggregation website.
Meanwhile, Ahern's latest book, The Year I Met You, is proving popular.
The story of a workaholic who is forced to take leave from her corporate job, was at the top of the Irish paperback charts last week and has sold 1,103 copies here and 2,989 in the UK. It has also been nominated in the Most Popular Fiction category of the Irish Book Awards.
