Edit:

Just found more on a website:

Eponine Thénardier is a very well-loved figure in the Les Misérables musical and novel. In the musical, her age is unknown, but she's 16 in the book. In the book, she has two siblings named Azelma and Gavroche. As a young girl, Eponine was spoiled by her parents, Madame and Monsieur Thénardier, who owned an inn. Her parents treated little Cosette, who worked for them, practically like a slave. They always compared her to their lovely little Eponine. But unfortunately for Eponine, the tables are about to turn. In the second act, things are different. The Thénardiers have lost their inn, and the family has to rely on Monsieur Thénardier's gang of thieves (which Eponine is part of ) for money. Now Eponine is the one who is poor and dressed in ragged clothes while Cosette is living a comfortable and nice life. Eponine is completely in love with a student named Marius Pontmercy, but he doesn't know this and in his eyes they are just friends. Sadly for Eponine, Marius actually falls in love with Cosette instead which causes Eponine to be really jealous of Cosette. When Marius is preparing at the barricade, Eponine disguises as a boy and sneaks in. He asks her to deliver a letter to Cosette, and on the way back to him she is shot. She dies in his arms.
