Seventeen-year-old Tan Lee thought living with his crush was awkward enough, until his ex-girlfriend showed up with stolen goods.After Winter Woo's dad died, she and her mom rented rooms in the Lees' house so they could stay in Palo Alto, California. Although the attraction between the Chinese American teens is mutual, Tan and Winter are mindful of their position as landlord and tenant and agree to remain platonic. When all three parents leave for a Maui vacation, Tan braces for a week of being around Winter with only Sana, his 5-year-old sister, as a buffer. Things go smoothly until the unexpected arrival of Rebecca Tseng, Tan's ex, whose wealthy, controlling parents whisked her home to Shanghai several months ago. Rebecca has run away with her father's Tang dynasty gold coins to pawn to fund her new life. But after Winter's 911 call-an attempt to get legal protection for Rebecca that instead draws the attention of men sent by Rebecca's father to capture her-they're all forced to flee. The ensuing chase takes the foursome around the Bay Area as they try to protect the coins-which are not what they at first seem-from their pursuers. Cryptography enthusiast Tan is better at cracking codes and ciphers than sorting out his feelings. His romantic dithering occasionally trips up the otherwise action-packed adventure, complete with hostages and an all-out rooftop showdown.A fun romantic thriller that offers plenty of excitement.
