So my daughter was suitably embarrassed when the teacher told her it was really good and really funny. She particularly liked the setting of a Dyson Sphere.
She was asked if she just saying that? No - because if she thought it was rubbish, she would have said nothing. And she's only reached Chapter 7, and it's only after that, that the story really kicks off.
If she thinks the ending is good, she's going to buy a hard copy (she's got a kindle one) and ask me to sign it on parent's night.
So the second thing?
My brother-in-law has bought a lot of copies (though they didn't affect the Amazon ranking) and got me to sign them.
He knows people who know people who know people (I'm not sure how many links are in the chain) and those copies are going to those people.
Then on the 4th of November, that's when the book club of my mother-in-law get told to buy it.
