Ex Marks the Spot

It's always been Gemma and her mom against the world — she thought all her grandparents, and her ties to Taiwanese culture, were long gone. Then a stranger arrives with the news that her grandfather has just died, along with the first clue in a treasure hunt that could lead to Gemma's inheritance.

The catch: she has to travel to her grandfather's home in Taiwan to solve it, and the only way she can get there is by asking her ex and longtime rival, Xander, for help. Swallowing her pride, Gemma finds herself racing through Taipei's streets chasing clues, discovering that the hunt is really about her family, her roots, and the boy she never quite got over.

A YA rivals-to-lovers romance from Gloria Chao, blending puzzle-box adventure with a vivid Taiwanese setting.
