The Lucky List by Rachael Lippincott,

Three years after the death of her mother, Emily feels adrift. The summer before her senior year brings additional upheaval: a breakup with her boyfriend, Matt, and her father's decision to sell their family home. While sorting through her mother's belongings, Emily discovers a bucket list her mom had created during her own senior year.

Encouraged by Blake, the daughter of her father's best friend who has recently moved back to town, Emily embarks on a mission to complete the list. As they check off each item, Emily begins to reconnect with her adventurous spirit and forms a deepening bond with Blake—one that challenges her understanding of herself and her past relationships.
