Unclear if you are asking about nuclear physics (i.e. the behavior 
of quarks and gluons when they are mainly color singlets in the 
form of protons and neutrons effectively exchanging mesons) or 
particle physics (i.e. the behavior of what used to be called 
"elementary" particles).

There is a "standard model" for particle physics described in all 
recent particle physics text books.  Which one you like is a 
matter of taste.  A working knowledge of quantum field theory is 
needed to appreciate this model. Its predictive power is outstanding 
as long as the energy of the interactions is high enough that one 
can calculate an answer.  It has yet to be able to calculate the 
mass of a proton; the low energy sector is really untested.  

Nuclear physics is basically the low energy sector of QCD, with 
the complication of having lots of particles interacting with 
one another.  The most complete description of the field is 
probably a pair of massive (and expensive) tomes: deShalit and 
Feshbach (Theoretical Nuclear Physics Vol. I, Nuclear Structure) 
and a new book by Feshback (basically vol. II on reactions, but 
I do not think it is called volume 2).  This material requires a 
good working knowledge of quantum mechanics with more of an 
emphasis on many-body theory than field theory altho the latter 
is helpful at times.  It is an intense book.
