The Chrysanthemum, the Cross, and the Dragon (Ring of Fire)

In Iver P. Cooper's latest alternate history novel, a new contribution to Eric Flint's 1632 Universe, the romance between Juan Cardona, an officer in Spain's Manila garrison, and Huang Mingyu, a young, beautiful Chinese woman, is threatened when a Dutch-Japanese force launches a surprise attack on 17th century Manila. Manila falls and Juan is rescued by Huang Mingyu, who proves to have hidden talents and connections. It is then up to Juan warn the incoming Manila galleon of the Dutch-Japanese threat before it blunders into Manila Bay, and then to prove his worth to Mingyu's family, Who have interests of their own in the region.... Will true love prevail when Japan (the chrysanthemum), Spain (the cross) and China (the dragon) come into conflict? For readers unfamiliar with the 1632 universe, it posits a cosmic catastrophe -- the RIng of Fire -- that throws the West Virginia town of Grantville into 17th century Germany. By 1633, the ripples caused by this event have reached East Asia, and the Japanese are determined to forestall the missionary-instigated Shimabara Rebellion of 1637.
