Fizzy is the daughter of divorced parents. Her father has remarried and her mother is in a serious relationship. Fizzy is also an excellent cook -- so good that she's entering the Southern Living cook-off. But she has other struggles to contend with. At school, she doesn't have any real friends, and then her mom announces that she's marrying her boyfriend, Keane (whom Fizzy dislikes). Fizzy also has to shuttle between both parents' homes, and she's constantly feeling like the "leftover" child since both her parents are moving on and forming new families.
I've had Solving for M on my TBR for a long time now! Mika and her mom are used to things just being the both of them because her parents divorced when she was a baby. Her dad remarried soon after, and her mom hasn't yet. She's a new middle schooler and is enjoying her math class, although the new pod system in their school means she isn't in the same group as her best friend. Their math teacher is very engaging and asks the kids to keep a semi-private math journal for the math problems they will do during the school year. All is well until Mika's mom discovers a spot on the back of her leg, which turns out to be a melanoma.
