Lisa McKormic lives in a world ruled by half-demons, and her family has just entered the elite upper-ranks of society. The McKormicks strive to further their rank by summoning one of the realm's most rare, powerful and precious creatures: a dragon. However, their plans are set back by turmoil, and between wicked curses, vicious rivals and rampant deception, the family struggles to keep together. Despised by her other siblings and scorned by her mother, Lisa looks for compassion from her favorite brother, John. When John convinces their parents to let Lisa participate in the dragon-summoning ritual, the events that ensue change Lisa's life and the McKormick family forever...

Environmental changes caused by LIPs and SLIPs include rapid global warming, global cooling ('Snowball Earth'), oceanic anoxia events, mercury poisoning, atmospheric and oceanic acidification, and sea level changes.Continued research to characterize the effects of these extremely large and typically short duration igneous events on atmospheric and oceanic chemistry through Earth history can provide lessons for understanding and mitigating modern climate change.Large Igneous Provinces: A Driver of Global Environmental and Biotic Changes describes the interactions between the effects of LIPs and other drivers of climatic change, the limits of the LIP effect, and the atmospheric and oceanic consequences of LIPs in significant environmental events.Volume highlights include:* Temporal record of large igneous provinces (LIPs)* Environmental impacts of LIP emplacement* Precambrian, Proterozoic, and Phanerozoic case histories* Links between geochemical proxies and the LIP record* Alternative causes for environmental change* Key parameters related to LIPs and SLIPs for use in environmental change modelling* Role of LIPs in Permo-Triassic, Triassic-Jurassic, and other mass extinction eventsThe American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity.
