This was amazing! Such a great summer mystery type read, with family & friendship at its core. Each chapter(besides chapter 1 which is titled the type of memory our MC has, chapter 2 that is just titled “The Brain”, & the last chapter which is “Lulu’s Journal)is titled a part from our brain. Then the 1st paragraph of that chapter explain what that part does, & usually our MC explains how it relates to memories. I learned so much about the brain alone reading this! I LOVED that. A diagram of the brain is even at the beginning of the book! There’s apparently SO much I don’t know, & that just makes me eager to learn more. There’s history to this story as well, with what our MC Lulu uncovers about her Grandma’s past. Everything about the mystery of her past, & the journal, etc. was so intriguing & just fascinating to me. Hooked me. Plus the history of the world the Grandma was living in during that time, & what her country,but especially what she, went through. So many important themes & relatable issues in here. Such as not fitting in, feeling “different” in some way like an outsider, family secrets, child loss(& what it can then do to a family), divorce, feeling invisible, how important some grandparents become in some kids lives, & Alzheimer’s. There’s just so much GOOD in here. Engaging writing, thought provoking, amazing pace, & incredible characters. I love the friendship between Lulu & Olivia. Especially how much closer this mystery brings them, & helps Lulu realize that she can really count on Olivia. That she won’t think she’s “too weird” because of her memory, & stop being her friend like she thought before. Also, Olivia shows her that just because someone is always smiling acting like everything is great-that isn’t always the case, & we should always check to make sure our friends are ok no matter the outside appearance. Then the friendship that forms between Lulu, Max, & Olivia as they team up to solve the mystery. Again, Lulu learns that appearances don’t always mean what they appear. Max’s smirk, for example, wasn’t what she thought at all. She misjudged him over & over, & he ended up becoming a great friend. The core feeling of this story is family. Wanting to be seen & loved by family, wanting to protect the family that DOES see you & love you, & feeling powerless sometimes as well. Life basically. Such an amazing read. HIGHLY recommend. STUNNING cover by Aveline Stokart too.💜
