The First Fifteen Lives of Harry August is a novel by Claire North, a pseudonym of British author Catherine Webb, published in April 2014.

[3] Harry August is born in the women's washroom of Berwick-upon-Tweed station in 1919, leads an unremarkable life, and dies in hospital in Newcastle upon Tyne in 1989.

He then finds himself born again back in 1919 in the same circumstances, gaining the knowledge of his earlier life at an early age.

He is not alone and is soon contacted by the Cronus Club, an organization of similarly affected members, who look after him in childhood in subsequent lives.

With knowledge from previous lives, he easily becomes a professor of physics at the University of Cambridge, where he meets an intelligent undergraduate student named Vincent Rankis.
