There is not much here when it comes to potentially concerning content.
It is handled really well, but some parents will want to know that the main character’s mom passed away in a car wreck. This has devastated the lives of this child and his father, which has caused a serious strain on the father-son relationship. There is also a scene where someone tries to break into their home at night while they are sleeping, a potentially scary thought for a child. Later there is a burglary in which an older person is hurt and eventually passes away. These things are kept “light” and the audience is certainly in mind here, but we want to make sure you are aware.
There are quite a few references to ‘swearing’. These all fall into the category you might think of as alternatives to what would be called swear words. Grady (the main character) remarks that his friend Clemmie isn’t allowed to swear, but usually doesn’t let that stop her. The other part of their trio, Theo, says the name of famous architects in place of swear words, a running joke that comes up throughout. Another time Thad uses “Holy Greek Revival” in the same way. Someone “inwardly cussed”.
A few other items to be aware of:
A character says of a recently deceased lady, “I wonder if Kooky’s ghost is digging up flowers for her heavenly mansion”. Later Thad is afraid to be in a graveyard. They joke about ghosts to mess around with him. Thad says that touching the gravestones is “bad mojo”.
A story mentions someone being run over by a train.
The following expressions are used: “stubborn enough to make a preacher cuss” and “uglier than sin”.
The story makes a passing reference to “The Addams Family” and the term zombies is used once.
Clemmie uses several insult type remarks when frustrated by something one of her friends said.
The following words appear multiple times: “stupid”, “idiot”. Readers also see “crap” used once.
