Item from From Blood and Ash by Jennifer L. Armentrout
The supernatural bond between wolven and their bonded Atlantian — a soul-deep connection that links life, loyalty, and instinct across two beings.
The wolven bond is an ancient pact made manifest in blood and magic. When a wolven bonds to an Atlantian, their lives become intertwined — the wolven can sense their bonded's emotions, location, and danger, and will fight to the death to protect them. Kieran is bonded to Casteel, and later to Poppy through the Joining, creating an unprecedented three-way bond that reshapes what everyone thought they knew about wolven magic.
