Synopsis
In the rain-slicked gloom of the Obsidian Tower, Mateo Cruz is nothing but a punching bag for the capos—a "Mouse" scurrying in the shadows. But a stolen maintenance key unlocks a brass service elevator that bridges two realities, offering Mateo a glimpse of a world where he rules the city and holds the untouchable Isabella Vesperi in his arms. When a violent coup threatens his original world, Mateo must channel the strength of his alternate self to rewrite a deadly fate, even if it means breaking the barrier between who he is and who he could be.
