The Curse of the Wishing Coin. Jitter Jumpers, #30

Thirteen-year-old Trinity has always seen coins as more than currency; they are artifacts of history, each carrying a story. But in the dusty corners of "Ye Olde Curiosities, " she finds a coin that doesn't just tell a story, it demands one. When Trinity makes a seemingly harmless wish, she discovers the coin's "final, devastating trick." It doesn't just solve problems; it performs an "Erasure, " removing people and memories from existence as if they never were.
Now, Trinity is a prisoner of the coin's chilling touch, left alone with the echoes of a life she can no longer reclaim.
