Twins who were seperated at birth meet before they were supposed. They are meant to save the world, but now they need protecting. Alexus and Layla go through the change of being only children to sisters, fighting off dangerous creatures, and falling in love. Also, they still have another year of high school. Put that all together and you get two pissed off, stressed out teenagers who are bound to be rebelious. Did I mention that they are guardian angels who have special powers that don't kick in until they turn eighteen.
