Merci Suárez is a sixth-grader whose life is full of changes. She has different teachers at school, new responsibilities as a Sunshine Buddies volunteer, and her friendships with the kids in her class suddenly got a lot more complicated. But the most worrisome change of all is her Lolo (grandfather), who suddenly starts acting strangely and forgetting people's names. This is a touching story not just of growing up, but also of coming to terms with a loved one's illness, in this case Alzheimer's disease. I loved the portrayal of Merci's family. They don't always get along but the love they have for one another is very real. Merci's struggles at school, including dealing with a mean girl, will also resonate with young readers.
