Ex Marks the Spot is an adventurous and action-packed story. When Gemma learns that her estranged grandfather passed away and left her a mysterious puzzle, she’s determined to follow the trail all the way to Taiwan. If the hunt ends in funds to pay for college, she needs it. But how will she get there? Gemma is forced to ask a favor from her sworn rival, the annoying Xander. As Gemma retraces her grandfather’s steps, what will she do when she starts to form a connection with Xander?

Ex Marks the Spot is such a fun book! Gemma and Xander have a great rivals-to-lovers arc and rebuild a solid friendship along the way. I loved how Gloria Chao also explored the importance of connection to your roots and how to find your place when you feel stuck in between two cultures. Through the puzzles, Gemma gains a deeper understanding of her Taiwanese heritage and the secrets her relatives held. Gemma and her mom have a loving relationship, reminiscent of Lorelai and Rory from Gilmore Girls. I really enjoyed the twist at the end with Gemma’s grandfather and the secrets that are uncovered. I feel like I went on a vacation to Taiwan and devoured all the delicious food that Gemma and her friends do! The descriptive writing is excellent and mouth-wateringly good when it comes to the food. The puzzles on the treasure hunt were so clever!

Readers who enjoy rivals-to-lovers, family secrets, and puzzles that lead to adventure will love Ex Marks the Spot.

Thank you to Gloria Chao, Viking Books for Young Readers, and Netgalley for a free ARC in exchange for an honest review.
