Shadow Realms. Doran Witches

A dissertation, a war mage, and a crack in the material world make for an interesting research trip. Kells Holland travels to New York on the trail of the infamous Doran witches, in the hopes of interviewing them for her anthropology dissertation. What she finds are time portals, an unplanned trip to the 1920s, and the man who has plagued her psychic visions for years. While in the past, Kells stumbles across information that the time portals are being opened by those of the shadow realms-a dangerous race that lives in an alternate dimension.
Malachi Sayer has fought the forces of the shadow realms since his recruitment to the Convention of the Rose Hand years before. Keeping his profession secret from his family hasn't been easy. Even less so given the attacks by the shadow beings have escalated. Now, a woman from his visions is at the mercy of darkness and he must go into their very depths to save her or risk losing her forever. Kells and Malachi must team up to keep the shadow realms from leaking into our world, even as the events that will tear them apart are rocketing ever closer.
