A witty, fast-paced YA sci-fi adventure packed with action, humor, time travel, and heart, led by an unforgettable, strong female protagonist.

      “I’m synthetic perfection in theory—with strength, speed, and vision beyond human limits. But inside? I’m a chaotic mess of doubt and high-strung static.” —Tianna

Nineteen-year-old Tianna Brooks is a synthetic human and a NASA Special Operations captain with one mission: save Earth before time runs out. She’s also sarcastic, anxious, and practically incapable of lying. She relies on math, and math doesn’t lie. Okay, she may have spoiled a few surprise parties.

Her mission sounds simple: travel sixty years into the past and give the Talions the warning they need to destroy their shared enemy years before the enemy ever reaches Earth. Tianna calls it a twofer. A save-the-planet special.

Naturally, everything goes wrong. Her teammate Zach is captured, the clock is ticking, and Tianna’s “simple” mission becomes a rescue operation through alien tech, palace guards, lions, and a past she can’t outrun.

If Tianna fails, Earth doesn’t get a second chance.
