I feel it worthwhile to quote from the Introduction to this novel, Horror d’Oeuvres: Bite-Sized Tales of Terror so that readers know what they are getting into. I came to this collection via Tobias Wade. He publishes a couple of fantasy/horror/twisted tales per week. I get those free in a weekly email. Tobias Wade is listed as an author of this edited anthology. One of his emails recommended this collection. It has 61 pieces of short fiction plus three bonus stories. My (hopefully relevant quote):

“This anthology was born from a rogues gallery of the best authors from Reddit’s premier horror flash fiction community, /r/ShortScaryStories.” (loc 170-172).

“This charity anthology … All revenue generated from the sales of eBooks, physical books, and audiobooks will be donated to Scares That Care!, an approved 501(c)(3) charity which fights the REAL MONSTERS of childhood illness, burns, and breast cancer by helping families that are experiencing these extraordinary hardships cope with the financial burden. It’s a 100% volunteer charity; meaning all donations are given to those who are in need; no CEO salaries, no overheads. Donations will be made on a quarterly basis for one year following the publication date of this collection. All information on the donations, sales numbers, and all other pertinent information will be available on www.reddit.com/r/Human_Gravy.” (loc 175-180).
