All the Summers In Between by Brooke Lea Foster is a captivating novel that is full of complex friendships, and coming-of-age stories, and weaves together themes of self-discovery, loyalty, and the power of human connection during a transformative era.

Friendships are complicated, and based on the summary and the foreshadowing, I was waiting for the big devastating incident that made Thea and Margot not talk for ten years. While I found myself interested in the plot, I was not interested in the characters. I wasn't very invested in their friendship forming in our earlier timeline and I definitely wasn't understanding how Thea would drop everything to help Margot after all those years of silence. I'm glad Thea could trust her, because I don't think I could have.
As the story of 1967 unravels, it doesn't make the 1977 timeline make much more sense and just makes Margot look even more manipulative and Thea seem to have even less of a personality.
