The Library must have a librarian…

Archimedes is no ordinary library. Its ceilings shimmer with stars, its books heal hearts, and it appears only where it is needed before vanishing without a trace. Whenever it moves on, the world forgets it ever existed–along with the family bound to it.

In London, after her parents are found dead under mysterious circumstances, Seraphine Finch inherits Archimedes and the burden of becoming its last custodian. Now the fate of the library rests with her alone.

But when she meets Sebastian Ellerbrook, a charming patron haunted by a dark past of his own, Seraphine begins to imagine a life beyond the library, even though their ending has already been written: the moment Archimedes moves on, he'll forget she ever existed.

As others seeking Archimedes draw closer, Seraphine must choose between protecting the greatest wonder the world will never remember... or risking everything for a love destined to forget her.
