Iveliz explains it all
(Book)

Seventh grade is going to be Iveliz’s year. She’s going to make a new friend, help her abuela Mimi get settled after moving from Puerto Rico, and she is not going to get into any more trouble at school. . . . Except is that what happens? Of course not. Because no matter how hard Iveliz tries, sometimes people say things that just make her so mad. And worse, Mimi keeps saying Iveliz’s medicine is unnecessary—even though it helps Iveliz feel less sad. But how do you explain your feelings to others when you’re not even sure what’s going on yourself?
