A monster spreads madness through the streets of Shanghai. It is the autumn of 1926, and Shanghai is poised at the brink of transformation. Foreign powers have carved out portions of the city for themselves; what remains is divided between two feuding gangs, the Chinese Scarlet Gang and the Russian White Flowers. Eighteen-year-old Juliette Cai has returned home from New York City, wreathed in a reputation for ruthlessness and ready to step into her role as heir to the Scarlet Gang. Four years ago, a betrayal by the White Flowers heir, Roma Montagov, a young man of 19, led to the deaths of countless Scarlets, and Juliette is determined to avenge her gang. But when a lethal contagion strikes the city, targeting Scarlets and White Flowers alike, Juliette and Roma grudgingly agree to cooperate on an investigation in order to save their city. The slow-burning romance in this book takes a back seat to the gripping mystery grounded in immersive historical detail. Allusions to Romeo and Juliet are evident in names and specific scenes, but familiar themes of family, loyalty, and identity bear new significance in Gong's inventive adaptation. Language is a tool wielded deftly by the multilingual characters, who switch easily among English, French, Shanghainese, Russian, and more, with Mandarin as the primary dialect for Chinese phrases. A strong supporting cast that includes a trans girl completes this striking debut. A must-read with a conclusion that will leave readers craving more.

This exciting debut brings readers to 1920s Shanghai--in the wake of the Opium Wars and the rise of communism--and an unforgettable reimagining of Romeo and Juliet where rival factions the Scarlet Gang and the White Flowers battle for financial and political control of their city. Juliette Cai, the fearless, ruthless, New York--educated heir to the Scarlets, will capture readers' hearts as she evades unwelcome advances from a shifty merchant, goes adventuring with her familial allies, and manages the rising conflicts between the Cais and their sworn enemies, the Russian Montagov family. Gong brings a high literary style and Shakespearean inspiration to a wholly unique world, from the vivid characterization of Roma Montagov and his mysterious connection to--and traumatic betrayal of--Juliette, to the banter, plot twists, and meticulous details on fashion. In addition to the expected tragic bloodshed, silver eyes have been spotted in the Huangpu River. Rumors speak of a guài (monster) that has the power to cause a suicidal madness in the people of Shanghai, and the gangs must work together to save Shanghai--and themselves. Amid the impressive world building, Gong's characters encounter vaccines in vials, xenophobic tendencies, and the interweaving of delightful Shanghainese dialogue, bringing to life a high-energy novel about how people can be monsters, too.

This mesmeric fantastical reinterpretation of Romeo and Juliet nestles the star-crossed lovers--renamed Roma Montagov and Juliette Cai--in an atmospheric mid-1920s Shanghai, where the Russian Montagovs, head of the White Flowers, and the Chinese Cais, head of the Scarlet Gang, have been embroiled in an age-old blood feud. Freshly returned from New York City, 18-year-old Juliette struggles to be respected as the heir of the Scarlets, since cultural sexism deems her hotheaded cousin Tyler, also 18, more worthy of deference. Meanwhile, Roma, 19, has never regained favor in his father's eyes after the bloody attack that wrested Roma from Juliette's good graces four years previously. But with colonial and communist tensions rising within Shanghai and "a strange madness"--linked to a rumored river monster--compelling men on every side to tear out their own throats, former lovers Roma and Juliette must reunite and surmount the bad blood between them if they have any hope of saving their city. Gong's incisive retelling imbues a thoroughly modern richness, with arresting prose and an inclusive cast. A lush, wholly original debut that will satiate Shakespeare aficionados and draw those seeking an engrossing, multifaceted historical fantasy. Ages 14--up. (Nov.)

Gr 8 Up--Insta-love reminiscent of Romeo and Juliet occurred four years before this story begins, leaving Juliette and Roma the bitterest of exes. Juliette Cai, daughter and heir to Lord Cai of the Scarlet Gang, has returned from New York to find Shanghai drastically changed from the city she and Roma talked about ruling. Foreigners have taken chunks of the city, leaving the Russian White Flowers--ruled by the Montagovs--and the Scarlets to fight over what's left. Now an infectious madness spreads through both gangs, leaving its victims to claw their own throats out. When Roma's little sister Alisa is infected, he teams up with Juliette to hunt down the cause and the cure. The cast of characters is diverse in ethnicities and identities. Roma and his cousin Benedikt are white, and their fellow White Flower Marshall Seo is Korean and queer. Juliette and her twin cousins Kathleen and Rosalind are Chinese; Kathleen is a trans woman. Gong combines star-crossed lovers with a gripping mystery, violent blood feud, and the glamour of 1926 Shanghai, turning the familiar play into a story readers have never seen before. Shakespeare fans will feel rewarded by parallels in the retelling, but Gong's writing has a sharp wit and offers new, thrilling stakes for all her readers. VERDICT Gong's debut is not to be missed. With a dazzling setting, a mysterious series of murders, and diverse, unapologetically criminal characters, this novel ranks with the greatest YA retellings.--Emmy Neal, Lake Forest Lib., IL
