Michel: Complex reflection groups and finite groups of Lie type

Here is a list of

-books which cover some material in my lectures:
'Reflection groups and invariant theory', by Richard M. Kane
'Representations of finite groups of Lie type', by F.Digne and J.Michel

-books which would be useful as preparatory material:
Lie Groups and Lie Algebras: Chapters 4-6 (Elements of Mathematics) Bourbaki, particularly chapter 5.
An introductory book on algebraic groups, e.g. the book of Borel, Humphreys or Springer on that topic.
Basic knowledge about representations of finite groups for instance 'Linear representations of finite groups' by Serre.
