Musing Monday: Stand-alone books or Series?

This week, Elena asks:

Do you prefer to read stand-alone books, or books in series? Do you stick with a series the whole way through or stop after the first instalment? Are there any particular series you enjoy?

I am at most in love with Series, but I do mostly read stand alone book even far more than series itself. It is hard to find good series and when you do find one, it always comes to an end when you least wanted it to. Plus the annoyance of a missing book in a series. lol
