A online book about a main female character named Violet

[Kasie]

I read it on Kindle Unlimited. It was a three book series based on three college male students who fall in love. The one I really remember had a purple cover and the main female name was Violet. The jock main male character goes to her for tutoring help and their relationship develops. The main female character had a stutter and parents died when she was younger and didn't have much family. I think the book was published around 2015 or 2016. It was a modern book

If you read it on kindle unlimited, you can look through your history in your amazon account to see what books you’ve previously read. Could it be “The Failing Hours
(How to Date a Douchebag #2)” by Sara Ney?

Yes! Thank you. I looked through my Amazon history, and I must have cleaned it. Thank you!

So it was Allison's suggestion: The Failing Hours?
