There’s only one these are actually the things her parents want. That becomes glaringly obvious when she spends the summer with her grandma and meets Colby Rivers. Colby is completely in control of her life. Sort of. She tends to overthink everything and doesn't have many close friends. Yet, when Mia Carmichael shows up, she sees something in Colby that no one else does. But falling for the girl who lives behind her grandma isn’t part of Mia’s plan. It can’t be. Can their relationship ever be more than stolen kisses and secret looks? Do they have a future or is this destined to end with the summer?
