I bought all four books, Doppelganger, Warrior, Witch, and Warrior and Witch thinking it was a four book series. Turns out Doppelganger and Warrior are the same book, and Warrior and Witch is the same book as the two Warrior and Witch together. Only a two book series. Great read, just don't waste your money the way I did.
