Chapter One

When heartbreak leaves Barry Allen and Caitlin Snow fractured in ways neither of them expected, fate weaves their grief into something more-something that could change the course of their lives, and the future itself. As Barry races to protect Central City and Caitlin struggles with powers that threaten to consume her, the two find comfort where they least imagined: in each other. But love in the shadow of loss is never simple, and their bond may prove as dangerous as it is unshakable.
