Markie Madden, born Marguerite Malone on August 19, 1975 in Midland, Texas, is the author of Once Upon a Western Way, Keeping a Backyard Horse, and My Butterfly Cancer. She grew up in Flushing, Michigan, where she began to write stories when she was a teenager.

She married in 1994 and now has 2 teenage daughters. She has 3 rescue dogs and a horse whom she enjoys spending time with. She is also a cancer survivor, battling leukemia (AML) in 2013-2014. She now resides in a small country town in Missouri, where she continues to write.

She hopes that her newest book, Keeping a Backyard Horse, will help prevent accidental mistreatment of horses, and help educate horse owners in taking care of their horse even on a budget. She raised and trained her horse Athena.

In 2014, she founded Metamorph Publishing as a way to self-publish her books, and she's now working with other indie authors as well. Her three books Once Upon a Western Way, Keeping a Backyard Horse, and My Butterfly Cancer are all available in print and for e-readers, and My Butterfly Cancer is also out in audiobook format. She can also be found on GoodReads, Scribophile, Shelfari, and Wattpad, as well as many other social media such as Twitter, Pinterest, Tumblr, LinkedIn, Facebook, and more.
