From The Official Les Misérables Site:

Former Broadway Kim, Rona Figueroa, will step into the role of Eponine in Les Misérables at the Imperial Theater June 3-23 1999. Figueroa made her Broadway debut as Kim in August 1993, playing the role until June 1995. She then played Eponine on tour with the national company of Les Misérables from April 1997-May 1998. Other credits include Grusha in The Caucasian Chalk Circle, Madeline True in The Wild Party and the title role in Turandot. Figueroa wrote and starred in the award-winning film short, Waiting in the Wings.

From Filipinas Magazine:

Rona Figueroa assumed the role after Florentino left the show in 1994. "My favorite memory of Miss Saigon is simply the experience of playing Kim," she says. "Every night at the end of the show, I was so emotionally wrung out that I was refreshed and empty at the same time, and ready to be filled again from the very bottom up. I think Kim is the most amazing female role ever written. It demanded and challenged all of my person, everything, all of my voice, all of my emotions. I felt so alive and I loved it!"

Even now, Figueroa looks back with amazement. "It’s truly surreal that I have starred in a Broadway show. I never aimed to do it, never trained. I just sort of went with the flow of my life, tried this out, tried that out. While I was in college, I went to an Asian club meeting and we were supposed to introduce ourselves and say our ultimate fantasy. I said ‘My name is Rona Figueroa and I want to sing on Broadway.’ And the room went ‘Oooooooh.’ But I was flippant! I never expected to get there! I never made it a serious goal because it seemed so far fetched... New York City! Broadway! Lead! Me?! Are you kidding? Then it happened a year and a half later. Is that magic or what?" Post-Saigon, Figueroa starred in Les Misérables and the film Dragonheart II.
