Ex Marks the SpotEx Marks the Spot

For Gemma's whole life, it has always been her and her mom against the world. As far as she knew, all her grandparents--and thus her ties to Taiwanese culture--were dead. Until one day when a mysterious man shows up at her door with two shocking things: the news that her grandfather has just recently passed, and the first clue to a treasure hunt that Gemma hopes will lead to her inheritance. There's just one major problem: to complete the hunt, she has to go to her grandfather's home in Taiwan. And the only way Gemma can get there is by asking her ex and biggest high-school rival, Xander, for help. But after swallowing her pride, she finds herself halfway across the world, ready to unearth her life-changing prize. Soon Gemma discovers that the treasure hunt is about much more than money--it's about finally learning about her family, her cultural roots, and maybe even finding true love.
