Waking the Ancients. Nemesis of the Gods Trilogy, #2

Egypt, 1908: University student Lizzie Charters accompanies her mentor, Dr. Emeryk Quintillus, on the archaeological dig to uncover Cleopatra's tomb. Her presence is required for a ceremony conducted by the renowned professor to resurrect Cleopatra's spirit-inside Lizzie's body. Quintillus's success is short-lived, as the Queen of the Nile dies soon after inhabiting her host, leaving Lizzie's soul adrift...
Vienna, 2018: Paula Bancroft's husband just leased Villa Dürnstein, an estate once owned by Dr. Quintillus. Within the mansion are several paintings and numerous volumes dedicated to Cleopatra. But the archaeologist's interest in the Egyptian empress deviated from scholarly into supernatural, infusing the very foundations of his home with his dark fanaticism. And as inexplicable manifestations rattle Paula's senses, threatening her very sanity, she uncovers the link between the villa, Quintillus, and a woman named Lizzie Charters.
And a ritual of dark magic that will consume her soul...
