León thought the Boundary had finally disappeared. Instead, he discovers that reality has begun remembering different versions of tomorrow before the present can even arrive.
When countless histories emerge at once, León, Tomás, Mireya, and Rafael are forced to confront alternate versions of themselves—and an unseen Observer that has been watching every possible reality from beyond the Boundary.
To save the worlds from collapsing into one another, they must make a choice unlike anything they have faced before: stop searching for the one true history and allow every world to remember itself.
But when the Boundary falls, something hidden inside León is finally released.
And it has been waiting for him from the beginning.
