the Mythic Bones Duology Shadow of Yew Tree

"You must heed our warning!""We have always rewarded surrender over sacrifice, Ronan.""You must remember this for what is to come-""And the promise of who you will meet in what comes after."It seemed a lifetime ago that Dr. Ronan Gallagher had succumbed to his obsessive need to uncover the deepest secrets of the Codex Druidicus, a grimoire of the very darkest magic. Though he'd tried to protect his closest friends from a threat that had followed them through multiple lifetimes, the choices made by the Druid doctor had been a betrayal of not only his friends but his own sacred oaths-a betrayal he would pay for with his life.Through the intervention of the Otherworld, he was given a second chance on this earthly realm to set things right. Yet, while the curse of the evil Sorcerer Cassius, ancient Child of Rome, might have been vanquished together with the Codex, the torturous tendrils born of Ronan's pride and obsessive weakness still thrive in the shadows, their reach extending further every day.When his fellow Druids learn of a massive explosion that has reduced a secret experimental Wraith facility to ruins, none can understand how Phoebe Ashburn, the sole survivor of the tortured experiments, has survived the blast's devastation ... and evaded their capture. With dark and volatile Wraith magic now trapped inside her-threatening her control and sanity-Phoebe is determined to discover how to rid herself of this inner darkness ... even if it means accepting the assistance of the very Druid doctor whose actions had led to her torture in the first place.
