Book my school librarian recommended, late 70's, early 80's.

Book was hardback, blue cover, white mountains. 

Main characters were small people like hobbits. I think one's name was Bin or Bik or Bek. 

They could communicate somehow with wolves, one was named Skie.

They find a Conjuror named Kel who has broken his leg. He seems to be fleeing from some enemies. 

That's as much as I remember. None of my school friends remember this book.
