I am a recent convert to Novenas. I was recently granted an impossible favour by St Jude (thank you St Jude!!) after doing a 9 hour Novena to him and and the Sacred Divine Heart.
I urge you all to consider saying a Novena if you are ever in desperate need of a miracle.
Here are some suggestions:
St Cyprian of Antioch: I call upon him as a protector of my business.
St Expedite: So many people write about him that all I can say is, yep he can be all that and a bag of chips if you need something done quickly or if you
have computer issues.
Our Lady of the Miraculous Medal: I got turned onto this manifestation of Mary by a group of three little old ladies in the Catholic gift shop. The next day my Grandmother gave me the medal as a gift, and I have called upon her Novena for myself and others many times.
Our Lady of Good Remedy: Similar to the above. Another group of little old
Catholic Ladies swore by her power. I am just now getting aquainted and like the cut of her gib. Extra good at freeing people from situations that keep them captive.
St Michael: A lot of people call on Michael of course for protection. I have also successfully been healed of agonising pain in minutes by Him.
St Homobonus: Useful for business.
St Jude: Helped me out of a situation where I really just had no idea what
to do next. Strong presence as well, that flame on his head is no joke.
Infant of Prague: Wonderful for when you need a quick financial resolution.
