Offensive garbage
Hard pass. This book is full of advice that is racist and ableist, as well as tone deaf and just plain lazy. She tells you to make your characters likable by making them disabled and garnering sympathy. But don't have them complain about their disability because no one cares.
The 'author' also tells you that hey, do you have editors, publishers and minorities breathing down your neck about your books being white washed? Just change the characters names from John, Bill, Susan, Ms. Jones and Dr. Willborough to Abdul, Sergej, Sunita and Dr. Wong. Ta da! Instant diversity.
A subsequent quote from the book:
"For a more significant change, pick one of the major characters- perhaps the MC's sidekick- and give him a different ethnicity. Consider what it means to belong to a minority in this society [...] or does he actually get advantages as the token ethnic person in 'politically correct' contexts, or because people imagine that everyone of his race has remarkable talent."
TRASH. Trash words by a trash person, who, when told people were finding her work offensive, typed "LOL" and said that people "who want to take offense at something will always find something to take offense at." She's churning out these books for money, without having published anything else that was widely/successfully circulated, and without any great character references except for unknowns from her own books, and people are following this terrible lazy ass advice.
Ugh.
