“An enthralling conclusion to this superb trilogy, displaying an exceptional combination of originality, magic, adventure, character, and drama.”—Kirkus Reviews (starred review) King Shrewd is dead at the hands of his son Regal. As is Fitz—or so his enemies and friends believe. But with the help of his allies and his beast magic, he emerges from the grave, deeply scarred in body and soul. The kingdom also teeters toward ruin: Regal has plundered and abandoned the capital, while the rightful heir, Prince Verity, is lost to his mad quest—perhaps to death. Only Verity’s return—or the heir his princess carries—can save the Six Duchies. But Fitz will not wait. Driven by loss and bitter memories, he undertakes a quest: to kill Regal. The journey casts him into deep waters, as he discovers wild currents of magic within him—currents that will either drown him or make him something more than he was. Praise for Robin Hobb and Assassin’s Quest “Fantasy as it ought to be written . . . Robin Hobb’s books are diamonds in a sea of zircons.”—George R. R. Martin “Superbly written, wholly satisfying, unforgettable: better than any fantasy trilogy in print—including mine!”—Melanie Rawn

Earth is home to an estimated 8 million animal species, 600,000 fungi, 300,000 plants, and an undetermined number of microbial species. Of these animal, fungal, and plant species, an estimated 75% have yet to be identified. Moreover, the interactions between these species and their physical environment are known to an even lesser degree. At the same time, the earth’s biota faces the prospect of climate change, which may manifest slowly or extremely rapidly, as well as a human population set to grow by two billion by 2045 from the current seven billion. Given these major ecological changes, we cannot wait for a complete biota data set before assessing, planning, and acting to preserve the ecological balance of the earth. This book provides comprehensive coverage of the scientific and engineering basis of the systems ecology of the earth in 15 detailed, peer-reviewed entries written for a broad audience of undergraduate and graduate students as well as practicing professionals in government, academia, and industry. The methodology presented aims at identifying key interactions and environmental effects, and enabling a systems-level understanding even with our present state of factual knowledge.
