Once and for All by Sarah Dessen (2017)

I always love Sarah Dessen, despite her pastel covers and completely forgettable titles. 

Louna works for her mother's wedding planning business one last summer before heading off to college. She meets reckless, open-hearted Ambrose at a wedding and has to decide whether she is ready to open her heart again after her first love affair's tragic end. 

As always with Dessen, the characters are SO rich. Louna's mother, her godfather, Ambrose and her best friend--all practically leap off the page. And the fun inside look into wedding planning is also delightful. Beautifully done as always.
