Jeremy Lachlan was born and raised on Wiradjuri country, in Griffith, New South Wales, Australia. A former bookseller, he completed his honours degree in creative writing at the University of Canberra in 2004, and now calls Sydney home.

His debut novel,Jane Doe and the Cradle of All Worlds, was the 2019 Australian Book Industry Award winner for Book of the Year for Older Children, and its second part,Jane Doe and the Key of All Souls, was shortlisted for the same award in 2021, but both of those pale in comparison to the $100 he once took home in a karaoke competition.

He came up with the idea for the Jane Doe Chronicles while lost in the Cairo Museum. Book three in the series, Jane Doe and the Quill of All Tales - the start of a new epic duology - is out now.
