How to Make Bad Books Good

The Compound

 * Make the characters more useful (especially with Eli's mom. Other than being beautiful, she's useless), and add more character development.
 * Eli is less of an controlling bitch.
 * Remove a lot of the parts were Eli is rude to his siblings.
 * Less product placement.

The Amazing Maurice and His Educated Rodents

 * Give "cat language" a better name. Seriously, "cat language".

Twilight

 * Remove the plot holes.
 * Not making Bella a Mary Sue.
 * Make Edward a teenage boy without vampire features.
 * Not making the vampires sparkle.
 * STOP. 👏 ROMANTICIZING. 👏 ABUSIVE. 👏 RELATIONSHIPS.

Junie B. Jones series

 * Better grammar and spelling. I get that she's a little kid, but I have never met kids who spoke like Junie B.
 * Junie B. is more likable.
 * Tone down the usage of "hate," "stupid," and "dumb."
 * Not making Junie complain constantly.
 * Have it teach good morals.
