Calina Gilbert - The Other Gilbert {EDITING}

Elena Gilbert was the living, doppelgänger of Katherine Pierce, or so we know. When you put Calina Gilbert into the picture you wonder how it is possible. There was always supposed to be one doppelgänger born every certain length of time.
"Only one,"
But after two Petrova doppelgängers are born, will this mean the end of the doppelgänger line?
Ever since the two turned seventeen, the world started falling at their feet. How can the world be balanced you might ask? To kill one doppelgänger.

The book gets better later in the book, trust me, at the start I was all over the place with writing but I have tried to improve.
