Her other books also contain the traditional themes of murder mysteries with dark humor, so keep reading to find out more about all the LJ Ross books in order.

Who is LJ Ross?

A self-publishing sensation, LJ Ross broke onto the scene relatively recently with her debut in 2015; however, she has quickly made a name for herself within the genres of mystery thriller, and romantic suspense.

Before she became an author Ross was a practicing lawyer in London. She grew up in Northumberland, England — where many of her books take place — and attended King’s College at the University of London for her undergraduate and postgraduate in law. She also studied in Paris and Florence.

However, she found herself dissatisfied after a decade working in law where every day was a battle and she longed for a change.

Previously, Ross had written short stories for her friends and family, but when the inspiration for Holy Island struck her, it was the first time she sat down to write a book. It became the first book in her DCI Ryan series. Ross did submit queries to traditional publishers and had responses in turn, but at the advice of her husband, also a lawyer, she chose to pursue self-publishing.

Her husband also has permanent recognition on every book cover in her choice of attribution as a tribute to his support. The second initial in LJ Ross stands for her husband James, while the first initial is for her first name, Louise.

Her debut became an instant international bestseller and twenty of her books have made it to the coveted #1 spot on the UK Amazon Bestsellers list. In 2020, Ross became the first self-published author to be short-listed for a British Book Award. Collectively, her books have sold more than seven million copies worldwide.
