Hi

I would very much second the recommendation of Gardner’s book. It has been
the best way to get into PLL’s for a *long* time. It is unique in that the current edition
 is still as relevant today as the book was when it first came out.

Some graduate-level students find Best, Stephens, and both Egan books hard to follow, while others find them very helpful.  I've never heard anyone complain about Gardner or Wolaver, except to the extent that they don't cover a topic of interest to the student.
