Ah, this is another fluffy contemporary right up my alley. I've had my eye on this for quite some time now and am glad I finally got to read it.
Haley's parents are divorced - have been for years - but, as one can expect, she's still struggling with it. Now her father has interrupted her summer plans and she has to spend a week at Disney's Fort Wilderness with his wife and her three-year-old half siblings.
When we first meet Haley, she doesn't feel like her father listens to her and, despite her efforts, fails to communicate her feelings. Then a seizure lands her in 1982. She needs to find a way back but there's just one problem, she doesn't want to go back.
She slowly comes to terms with her parents' divorce, even as she endeavors to give them the spark her father claims they were missing when they first met in 1982. When she gets back though, she isn't so angry with her dad. All of her problems aren't fixed, but her attitude changes. The character development was perfect for the few days covered in Summer of Yesterday.
Haley wanted a summer fling and finds it in Jason, the kind-hearted boy from 1982. I loved watching them become closer in the limited time they had. It was cute and light-hearted. I honestly attribute part of Haley's growth to Jason. There at the end, she didn't want to leave him and he didn't want her to leave either; but he understood that he had to let her go, so he did. It was sad and beautiful all at once.
The ending was sad and happy all at once. Haley developed a new understanding about her situation in life but she also lost Jason. Miss Triana, did a wonderful job writing a very satisfying ending.
