In the Blood — J.S. Malcom

Autumn Winters knows something that no one else knows. Now, she has to do something no one else would do. Autumn Winters has chased a race of supernatural beings from out of the shadows. Now, she's paying the price. Those same paranormal entities have become aware of her presence as a protector of the veil, and they'll stop at nothing to remove her as a threat. Burdened with knowing that the most powerful of her new enemies now inhabits her sister's body, and that this same creature could easily ensnare her as well, Autumn faces an impossible choice. She can either save her sister from a fate worse than death or free herself from a web designed specifically to trap her. Meanwhile, the clock is ticking as Autumn struggles to come up with a plan to vanquish a threat unknown to the rest of humanity. All she knows for sure is that it's down to her, the only woman whose blood holds the power to protect the veil between this world and another unseen by anyone but a realm watcher. In the Blood is the second book in the Realm Watchers urban fantasy series, where nothing is as it seems and only a thin veil exists between our world and another full of ghosts, vampires, magical creatures and other trans-dimensional intruders who walk alongside us unseen by anyone but the realm watchers.
