Last to Leave the Room is a new novel of genre-busting speculative
horror from Caitlin Starling, the acclaimed author of The Death of Jane
Lawrence.
The city of San Siroco is sinking. The basement of Dr. Tamsin Rivers,
the arrogant, selfish head of the research team assigned to find the
source of the subsidence, is sinking faster.
As Tamsin grows obsessed with the distorting dimensions of the room at
the bottom of the stairs, she finds a door that didn't exist before -
and one night, it opens to reveal an exact physical copy of her. This
doppelgänger is sweet and biddable where Tamsin is calculating and
cruel. It appears fully, terribly human, passing every test Tamsin can
devise. But the longer the double exists, the more Tamsin begins to
forget pieces of her life, to lose track of time, to grow terrified of
the outside world.
As her employer grows increasingly suspicious, Tamsin must try to hold
herself together long enough to figure out what her double wants from
her, and just where the mysterious door leads...
