Rebecca Moesta Anderson was born in Germany, to American parents and raised in Pasadena, California, where she lived until her early twenties. Moesta graduated with a Bachelor of Liberal Arts from Cal State L.A.. and shortly after graduation married a former classmate from Caltech, becoming Rebecca Moesta Cowan.
In 1981, the couple moved to New Haven, Connecticut, where they lived for one year until they moved to Darmstadt, Germany, until 1987. In Germany Moesta took graduate courses with Boston University and earned a Master of Science degree in Business Administration. During their stay in Germany she gave birth to her son, Jonathan, before moving back to the United States and settling in Livermore, California.
In 1989, Moesta took a position at the Lawrence Livermore National Laboratory as a proof reader and copy editor. There she formed a science fiction club in which she met her future husband Kevin J. Anderson. She divorced her first husband in 1990 and married Anderson in 1991.
The couple started working together writing science fiction novels and to date has written two Titan A.E. young adult novels, two high-tech pop-up books, and fourteen Star Wars expanded universe novels, the Young Jedi Knights series. The couple owns and runs the publishing company WordFire Press, and Rebecca is currently working on several new projects, including copy editing her husband's works.
