I should have added that the Gardner book is absolutely essential for 
anyone designing PLLs, IMO.

Best is excellent.  Chapter 9 is specifically devoted to higher-order 
loops (through 5th order).

Stephens covers DPLLs from a different angle than Gardner.

Egan marches to his own drum, so the way the subject is divided, the 
topics covered, and some of the notation does not necessarily match 
other texts.  These can be the hardest to follow, but Egan is very thorough.

Wolaver's book covers PLL basics comprehensively and is both a great 
introductory text as well as an excellent review text to jog the 
memory of an experienced PLL designer.

Different people learn differently, so a book that is ideal for one 
person is not necessarily the best for another person.  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.

Best regards,
