Parents need to know that there's not much to worry about in this novel. The family struggles with after-effects of the death of a parent and there is some sibling rivalry. There are also a couple of instances of boy-girl like typical of the age.
Positive messages:Samantha learns how to control her temper and her mother works on helping her daughters cope with the loss of their father.
Violence:Two girls get lost at the Grand Canyon, but they are found unharmed. A girl kicks a boy -- she says accidentally, he says on purpose.
Sex:A teen girl has a crush on a boy and tries to flirt with him. A middle-schooler starts to move past her "boys are gross" phase.
Language:Some name-calling and yelling among siblings and grade-school kids.
