Chess books about Light Piece Endgames

Knight and pawn endgames feature clever maneuvering by the knights to capture opponent pawns. While a knight is poor at chasing a passed pawn, it is the ideal piece to block a passed pawn. Knights can't lose a tempo, so knight and pawn endgames have much in common with king and pawn endgames. An outside passed pawn can outweigh a central protected passed pawn, unlike king and pawn endgames. A knight blockading a protected passed pawn attacks the protector, while the knight blockading an outside passed pawn is somewhat out of action.
Bishop and pawn endgames come in two distinctly different variants. If the opposing bishops go on the same color of square, the mobility of the bishops is a crucial factor. A bad bishop is one that is hemmed in by pawns of its own color, and has the burden of defending them.
