From the New York Times bestselling sibling duo behind The Last Tiger comes Alter Ego, a portal fantasy about a chronically ill teen who wakes up inside her favorite sci-fi series and must decide whether to follow the story she knows or write her own.

Wilma Oh has spent the last few years feeling trapped—by a severe chronic illness, the four walls of her bedroom, her own uncooperative body. Her only escape? The Reality Show, her favorite sci-fi series, which depicts a brutal, high-stakes world that’s basically Squid Game meets The Hunger Games in space.

Then the impossible happens, and Wilma wakes up inside The Reality Show universe.

She’s in the body of Kira, the story’s fearless hero…without Kira’s ruthless survival skills.

Armed with an obsessive encyclopedic knowledge of every plot twist, every alliance, and every death, Wilma is determined to stay alive by following the story beat for beat. But surviving this universe means making impossible choices—including killing to stay in the game.

And when Wilma’s actions begin to change the story, everything she thought she knew starts to unravel. The plot veers off course. The future becomes uncertain. And worst of all, Wilma finds herself falling not for the hero’s intended love interest, but for the story’s antagonist.

To survive, Wilma must do more than rewrite the ending. She has to let go of the story that once saved her—and choose her own.
