Leadership Theory and Practice Eighth Edition by Peter G. Northouse

In this fully updated Eight Edition of Leadership: Theory and Practice, 
a new chapter on Followership examines the central role followers play in 
the leadership process and unpacks the characteristics of both effective and 
ineffective followers. The new edition also includes a new Ethical Leadership Style 
Questionnaire and new coverage on the dark side of leadership and destructive leadership. 

Adopted at more than 1600 institutions in 89 countries and translated into 
13 different languages, this market leading text successfully combines an academically 
robust account of the major theories and models of leadership with an accessible style 
and special emphasis on how leadership theory can inform leadership practice. 
Peter G. Northouse uses a consistent structure for each chapter, allowing students 
to easily compare and contrast the various theories. Case studies and questionnaires provide students with 
practical examples and opportunities to deepen their personal understanding 
of their own leadership.
