A novena normally lasts nine days and in that time you should go to confession and receive Holy Communion at least once. You can do a novena to God the Father, Jesus, Holy Spirit, Our Lady, the Angels or any canonised or beatified saints etc depending on whom you have devotion to or what your need/request is. St. Anthony is a great one for answering requests quickly - although maybe I’m just biased!
So many good novenas to choose from! St Anthony is my favorite too, but that is just my personal bias too His can be found here at: forums.catholic-questions.org/showthread.php?t=181642
and there are a few other versions out there too, they can usually be found by doing a search in any good search engine.
Here is a link to several good novenas others have shared, if you do a google search here on CAF you will find so many more though!
