C.D. Muller (also under the pen name Crystal Summers for romance) was born on December 9th, 1990. From her love of Harry Potter, she wrote the first installment in the Armageddon Trilogy when she was fourteen. 

She graduated from Patagonia Union High School in 2009 and attended college to study Computer Science and programming. She participated in community events, such as writing plays for the Tin Shed Theatre and preparing presentations for elementary classes.

Her husband's death heavily affected Muller's writing and art. She almost gave up on both but ended up using her talents to help her cope with depression and anxiety.

She currently lives in Tucson, AZ, with her new husband, newborn son, and three cats. For more information, go to https://crystaldsummers.com for updates and her social media.
