Emerald Green is the third and final book in the Ruby Red trilogy.


Gwen has a destiny to fulfill, but no one will tell her what it is. She's only recently learned that she is the Ruby, the final member of the time-traveling Circle of Twelve, and since then nothing has been going right. She suspects the founder of the Circle, Count Saint-Germain, is up to something nefarious, but nobody will believe her. And she's just learned that her charming time-traveling partner, Gideon, has probably been using her all along.[1]
