Emily and her mom were always lucky. Every month they’d take her lucky quarter, select lucky card 505, and dominate the heatedly competitive bingo night in their small, quirky town of Huckabee. But Emily’s mom’s luck ran out three years ago when she succumbed to cancer, and nothing has felt right for Emily since.

Now, the summer before her senior year, things are getting worse. Not only has Emily wrecked things with her boyfriend Matt, who her mom adored, but her dad is selling the house she grew up in and giving her mom’s belongings away. Soon, she’ll have no connections left to Mom but that lucky quarter. And with her best friend away for the summer and her other friends taking her ex’s side, the only person she has to talk to about it is her dad’s best friend’s daughter, Blake, a girl she barely knows.

But that’s when Emily finds the list—her mom’s senior year summer bucket list—buried in a box in the back of her closet. When Blake suggests that Emily take it on as a challenge, the two set off on a journey to tick each box and help Emily face her fears before everything changes As they go further down the list, Emily finally begins to feel closer to mom again, but her bond with Blake starts to deepen, too, into something she wasn’t expecting. Suddenly Emily must face another fear: accepting the secret part of herself she never got a chance to share with the person who knew her best.
