I have been trying to learn about the representation theory of Kac-Moody algebras in positive characteristic. However, my usual reference for the subject (Infinite dimensional Lie algebras by Kac) assumes throughout that the field has characteristic $0$.

Trying to find new references online has lead to some interesting resources, but so far they all deal with the related group-theoretic structures e.g. linear algebraic groups (over a field of characteristic $p>0$) and the corresponding restricted Lie algebras.

Does anyone know where I could find an account of the representation theory of Kac-Moody algebras over a field of characteristic $p>0$?
