The pretty little streets of Montmartre are abuzz with a rumour. Apparently a mystery matchmaker known only as 'Paris Cupid' has somehow helped the city's most famous bachelor find love. But old-fashioned romantic Lilou is staying very quiet. She'd just wanted to set up her best friend and to get on with her life selling whimsical old love letters in Paris's famous St. Ouen market. She hadn't imagined her little Paris Cupid project could ever have attracted so many people looking for true heartfelt romance. Though the truth is that Lilou adores helping people find the right person. Even if her own love life is nothing short of disastrous. But then a message arrives. And it's just for her. Someone is in love with her. Someone who knows her secret. But they're keeping their own identity secret too. . . Could it be from cheerful talkative flame-haired Felix? Or quiet beautifully handsome Benoit? Or even Pascale - who drives Lilou mad every day? After so long of helping others find their soulmate is it time for Lilou to find love of her own in Paris herself?
