She cannot tell if this ability is a blessing, or a curse. Meanwhile, the nefarious cult, known as the Supernatural Liberation Movement is determined to expose Supernaturals for what they are, destroying them in their path--and this plan affects all types of supernaturals, from demons, to witches, to vampires. On the eve of the battle between the Otherworld and Supernatural Liberation Movement, the major supernaturals must come together to fight for their lives and for the existence of the Otherworld.
