Paris , France ( CNN ) -- Former Colombian hostage Ingrid Betancourt tells the story of her six-year captivity in a book due to hit the shelves Tuesday . Betancourt , a former presidential candidate in Colombia , was held for more than six years by Marxist rebels before the Colombian military rescued her and 14 others in 2008 . `` Meme le Silence a une Fin , '' or `` Even Silence Has an End , '' will go on sale around the world , the publishing house Gallimard said . In June , Betancourt filed a suit , asking for about $ 7 million from the Colombian government for the years she spent as a hostage . Betancourt and her family members say the government did not do enough to protect her . Betancourt was freed in a high-profile helicopter rescue mission in July 2008 . Colombian commandos posed as humanitarian aid workers to free the group , which included three U.S. military contractors and 11 Colombian police and military members . In a memoir published last year , the U.S. military contractors rescued along with Betancourt painted an unflattering portrait of the dual citizen of France and Colombia , describing her as someone who hoarded belongings and let her temper flare during their time in the rebel camp . CNN 's Sarah Goddard contributed to this report .
The book tells the story of her six-year captivity in Colombia . It is titled `` Even Silence Has an End ''
