Sickly fifteen year old Prince Psal, the son of the nature-blessed warrior-king Nahas, should have been named Crown Prince of all Wheel Clan lands. A priest-physician like his friend Ephan, Psal lacks a warrior's heart, yet he desires to earn Nahas's respect and become a clan chief. If he cannot do this, he must escape his clan altogether. But his love for Cassia, the daughter of his father's enemy, and his own weaknesses work against him. When war comes, Psal defends Ktwala and her daughter Mahari, wronged by Nahas, and speaks out against the atrocities his clan commits, further jeopardizing his future. And now the mysterious towers that keep humans safe from the Creator's ancient curse are rebelling. A prophecy exists-not that Psal believes such matters-of three great ones who will find the Constant Tower and break the power of the third moon. Could Psal, Ephan, and Mahari be those great ones? Psal must risk losing his father's respect to find his destiny, and with his friends face the dangers of the unmaking night to find the Constant Tower and save all of humanity. "Carole McDonnell is a first-class world-builder. A unique, powerhouse epic, The Constant Towers is a treasure trove of great characters, compelling cultural details and political machinations, all lovingly detailed in evocative prose. Yay!" - Stefan Petrucha, author Dead Mann Walking

The world's most experienced scientists and professionals working on cooling towers gathered at the 5th International Symposium on Natural Draught Cooling Towers to discuss the latest developments in this area and exchange knowledge and experiences. This book comprises 43 contributions on the latest developments in the field of natural draught cool

A comprehensive account of one of the main directions of algebraic topology, this book focuses on the Sullivan conjecture and its generalizations and applications. Lionel Schwartz collects here for the first time some of the most innovative work on the theory of modules over the Steenrod algebra, including ideas on the Segal conjecture, work from the late 1970s by Adams and Wilkerson, and topics in algebraic group representation theory. This course-tested book provides a valuable reference for algebraic topologists and includes foundational material essential for graduate study.

These proceedings comprise two workshops celebrating the accomplishments of David J. Benson on the occasion of his sixtieth birthday. The papers presented at the meetings were representative of the many mathematical subjects he has worked on, with an emphasis on group prepresentations and cohomology. The first workshop was titled "Groups, Representations, and Cohomology" and held from June 22 to June 27, 2015 at Sabhal Mòr Ostaig on the Isle of Skye, Scotland. The second was a combination of a summer school and workshop on the subject of "Geometric Methods in the Representation Theory of Finite Groups" and took place at the Pacific Institute for the Mathematical Sciences at the University of British Columbia in Vancouver from July 27 to August 5, 2016. The contents of the volume include a composite of both summer school material and workshop-derived survey articles on geometric and topological aspects of the representation theory of finite groups. The mission of the annually sponsored Summer Schools is to train and draw new students, and help Ph.D students transition to independent research.
