Shake

A fractured future. A family secret. The ultimate double-cross. The Great San Francisco Earthquake of 1906 leaves Allie without her crew, her parents, or a life to return to in 2018. Refusing to accept this, Allie dives into the rapidly closing wormhole—with her newfound half sister, Bel—intending to go back in time and save everyone. Except Mean Girl Bel has other plans. Bel hijacks the wormhole, taking them both to 2153. Now Allie is trapped in the treacherous landscape of Bel's "real time," where Bel's uber-powerful mom is in charge and has banned all time travel. Out of her element and out of her depth, Allie has to figure out how to get back to 1906 and make things right. Desperate, Allie secures the help of time monitor Flyx and his friends. Together they make a plan to circumvent the time travel ban and send Allie back in time. In order for the plan to succeed, Allie must avoid being "recycled" by Bel's mom, escape the clutches of Nazis who've taken over the city, and finesse her biggest con yet: convincing Bel to take her side. If you enjoy fast-paced time travel adventure, like Time Bound or The Rise and Fall of D.O.D.O., you won't want to miss the In Real Time series! Start with Quake, Book 1 and continue with Shake, Book 2, and Break, Book 3.
