The Boy on the Bridge

The Boy on the Bridge is set in the same post-apocalyptic fungal-infection universe as M.R. Carey's The Girl with All the Gifts but functions as a companion novel rather than a direct sequel. Published in 2017 by Orbit Books, it follows a different cast of characters whose story eventually intersects with events from the first book.

The Rosalind Franklin, often called 'Rosie,' is the armored mobile laboratory that carries the scientific and military expedition through a devastated Britain. Named after the real-world DNA researcher, it serves as both a research base and a vehicle for searching for information about the Ophiocordyceps fungal infection.

The Boy on the Bridge can be read independently, but familiarity with The Girl with All the Gifts enriches the experience. The two novels' timelines eventually converge, and certain revelations depend on knowledge from the first book.

The Boy on the Bridge was written by M.R. Carey, the pen name of British author Mike Carey, who is also known for his work in comics including the Lucifer series for DC/Vertigo. The novel was published in 2017 as a follow-up set in the same universe as his bestselling The Girl with All the Gifts.
