In this fourth and final book of the Oracle of Light series, Rahlys is lured into complacency by a visual misconception and her inability to detect the threat that lingers. Seeking a return to her true identity Melinda holds the key, and to protect those she loves shoulders the burden of confronting Droclum's evil essence alone. Only five year old Leaf Bradley perceives something is amiss. The lure of the key has far-reaching consequences stretching as far as the Devastated Continent. It may be up to Warrior Leaf to save the day. On Aaia it is a battle for individual dignity and personal freedom. With Captain Setas on their side, “Seek Heart, Not Soul,” Rojaire and his followers, including Theon's daughter Ilene, seek to escape the High Council's control. But the reawakening of Droclum's essence plagues their attempt to reunite with Theon and the others in their secret valley. Terrifying events unfold on both worlds, with challenges that will test strength and courage and melt the heart with love.
The phenomenal development of writing and literary creation among the francophone communities of eastern Canada has gone largely unnoticed and unprobed outside the fragmented land of Acadia. Writing Acadia attempts for the first time to observe from a distance the invention of literature in oral Acadia, and to interpret, assess and order the manifold manifestations of the transition from epic story-telling to writing as a means of nation-building. Having begun to write, modern Acadia has truly (re)written herself into existence, an existence now threatened by postmodern unwriting of literature. Destined not only for specialists but also and especially for readers with a general interest in literature, including students of all levels, Writing Acadia presents generous samples of Acadian poetry, drama and prose, with accompanying English translations.
In this account, Rodney Barker tells the full and terrifying story of a microorganism popping up along the Eastern seaboard—far closer to home than the Ebola virus and equally frightening. In the coastal waters of North Carolina—and now extending as far north as the Chesapeake Bay area—a mysterious and deadly aquatic organism named Pfiesteria piscicida threatens to unleash an environmental nightmare and human tragedy of catastrophic proportions. At the very center of this narrative is the heroic effort of Dr. JoAnn Burkholder and her colleagues, embattled and dedicated scientists confronting medical, political, and corporate powers to understand and conquer this new scourge before it claims more victims.
