OATH BOUND (Unbound #3) by Rachel Vincent
This is the cover for Rachel Vincent's third book in the Unbound series. She writes great urban fantasy books and her Soul Screamers (YA) and Shifters series are hugely popular. This cover keeps in line with the other book covers in this series but what stands out is the colours used. They are beautifully done and the model looks gorgeous. The UK cover is not out yet so until it does keep watching this space.
