Genie Wishes by Elisabeth Dahl
From the first day of fifth grade, Genie knows there will be good, bad, and in-between. The good? She's in homeroom with her best friend, Sarah. The bad? Sarah's friend from camp, Blair, is a new student at their school, and is itching to take Genie's place as Sarah's BFF. The in-between? Genie is excited to be elected to write her class's blog, where she's tasked with tracking the wishes and dreams of her class. But expressing her opinion in public can be scary--especially when her opinion might make the rest of her class upset.
One of the girls in Genie's grade is Anna Miles, and Anna has two dads. It's not really a plot point, but it's there. Genie's family is her dad and grandma.
As my kid put it, "It's a story of friendships changing. I loved it." Add your review of "Genie Wishes" in comments!
