Lorna Morello always dreamed of her wedding day but it wasn't until she met Nicky Nichols that she imagined her wedding would be with another woman. When their wedding is only days from their grasp, will Lorna's desire to have her dead-beat father's attendance cause an uproar? Lorna/Nicky. One-Shot. Disclaimer: I don't own the show, Mamma Mia, or the characters. All I own is the writing and story. Author's Note: So, I have been kind of obsessed with ABBA lately (hence the title of the story) and just recently watched Mamma Mia for the first time in a long while and was highly inspired to write a little (haha little haha) Lorna/Nicky one-shot that is rather loosely inspired from the movie. This was literally all written today, so, forgive me for any mistakes. I will read through tomorrow and revise what needs revised. *Cross posted on fanfiction.net and AO3 - this is the unedited version, so, there may be grammatical errors, words missing, etc.
