I've looked through at least a dozen.  For neophytes, the best of the bunch
BY FAR is Goldblatt, Topoi: the categorial analysis of
logic<http://digital.library.cornell.edu/cgi/t/text/text-idx?c=math;cc=math;q1=Goldblatt;view=toc;idno=gold010>.
 Don't be put off by the title.  He not only explains the stuff, but
he
explains the problems that motivated the invention of the stuff.  He doesn't
cover monads, but he covers all the basics very clearly, so once you've got
that down you can move to another author for monads.
