A split-second decision, a single time-skip. The world you know, gone in a blink. After the gripping cliffhanger escape in Lifespan of Star Light, Scout lands with a thud in the future. But it's not 10 years later, where she's supposed to meet her time-traveling friends. It's only four. In this "now," Scout finds only desperation and grief. Haunted by the consequences of her last jump, she panics--and when she jumps again, everything changes. Sucked backwards, Scout achieves the holy grail of time-jumping: traveling back through time. Now she's caught between finding the mother she left behind and time-skipping ahead to her only friend, Mason--but can her actions in this "new" past change the future?
