The Secret of La Rosa: A Mystery Adventure (Mogi Franklin Mystery Book #3)

Uncover Ancient Secrets and Hidden Dangers in The Secret of La Rosa!—A Thrilling Middle-Grade Mystery Adventure!

What begins as a simple cross-country ski trip turns into a chilling adventure when Mogi Franklin and his sister, Jennifer, are caught in a brutal blizzard. Struggling to survive, they stumble into a hidden valley—home to an ancient hacienda, a bustling Spanish family, and a strange village untouched by modern life. No cars. No electricity. And no way out.

What started as a vacation to help his Granddad with holiday preparations now becomes Mogi’s toughest mystery yet. Accused of stealing a sacred religious icon tied to a legend of lost Spanish gold, Mogi must navigate shadowy figures, secret societies, and a town full of secrets. As he fights to clear his name, Mogi is also confronted by unresolved grief from his grandmother’s death the previous Christmas.

Is this valley real, or just an illusion? And can Mogi solve the mystery of La Rosa before it’s too late?

The Secret of La Rosa is the third thrilling book in the Mogi Franklin Mystery series, perfect for middle-grade and young-adult readers who love adventure, history, and fast-paced mysteries.

Join Mogi on his most personal—and dangerous—adventure yet!
