I’ve been asked to post the contents guidelines from Amazon so that you get an idea and maybe will be able to tell me what’s wrong in BUSCAFUSCO: Fun & Games.
This is indeed an interesting read, I guess, because after all it has to do with my writing life. 

The actual document is pretty large, but what’s pertinent is – I think – the following, that goes under the Offensive & Controversial category:

Violence, Intolerance, and Hate

• Products that contain violent or offensive material that has no historical significance. Amazon reserves the right to make a determination on the historical value of the item.
• Products that promote, incite, or glorify hate or violence towards any person or group. This includes products that contain violent or offensive material that has no historical significance. Amazon reserves the right to make a determination on the historical value of the item.
• Products that promote or glorify suicide
• Products related to terrorist organizations
• Products that promote or glorify people that have been found guilty of violent or sexual crimes.

Intolerance

• Products that promote intolerance based on race, religion, and sexual orientation.
• Products that contain racially derogatory language

Human Tragedies and Disasters

• Products related to human tragedies and natural disasters

Child Abuse and Exploitation

• Products that depict child abuse/exploitation
• Products intended for use by children that contains adult content, profanity and/or sexual references
• Products depicting children or characters resembling children in a sexually suggestive manner
• Products marketed to or targeted at kids or teenagers that are age-inappropriate

And really, I can’t say there’s anything like that in my Buscafusco stories. Granted, this new story marks the first appearance of the Chinese Triads, but there is no racist content I can think of. I purposefully avoided derogatory terms, despite the fact that one of the characters is the sort that would use them. Because only a fool chooses to risk and offend his readers on a matter of authenticity.

Anyway, we are still here waiting.
The plot thickens.
