Book 4 of The Telepathic Clans Saga Corwin has led Clan O'Neill for one hundred and fifty years. Nearing the end of his long life, he names a twenty-three year old girl as his heir. Not only is Brenna a member of Clan O'Donnell, she's also a succubus, and many people disagree with his choice. When Corwin dies, his son Hugh launches an open rebellion. But Brenna is named heir not only to O'Neill, but also to Clan O'Byrne, where Clan Chief Fergus's oldest son Andrew joins with Hugh and Finnian O'Neill in their rebellion. Faced with war on two fronts, and rebels using terrorist tactics that capture the attention of the human press and authorities, Brenna must fight off assassination attempts while trying to consolidate her rule. As if all that wasn't exciting enough, her friend Irina is the target of repeated kidnapping attempts by members of a Russian Clan. Hoping to protect Irina, O'Donnell mounts an operation against the Gorbachev Clan. But the situation in Russia is no more stable than in Ireland, and they discover Irina is at the heart of the Russian Clans' internal plots. Confused yet? Be glad you aren't Brenna and Rebecca, as they-along with Rhiannon, Irina, and the Irish Clans-attempt to sort through the mess in Succubus Ascendant, the action-packed conclusion of The Telepathic Clans Saga.
