Hannah Kollef was born on the anniversary of Genghis Khan's death. She believes this is responsible for her poor table manners and love of pillaging. Hannah is proud to hold the title of Master of Science, even though that science is library science and the only thing she has mastered is a proper Librarian Glare when people organise their bookshelves by colour. While travelling Europe as an English teacher she self-published three YA fantasy novels inspired by fairy tales and the dangerous histories behind them. "The Danger in Bohemia", her first romantic thriller for adults, was published with Dreamspinner Press in 2016. After a break to move to the UK and settle permanently, she is back at work on her next series for adults, an urban-fantasy dulogoy described as Neverwhere meets Winter's Orbit. ​In addition to her novels, Hannah has been published in various magazines including In General magazine and Hometown Quarterly. She has also worked as a freelance copywriter, editor, and social media consultant. She currently lives in the UK where she analyses data during her day job and at night manages the feeding schedule of a very demanding, mildly overweight cat.
