The Native Star, book 2 : The Hidden Goddess
M.K. Hobson2011

Like it or not, Emily has fallen in love with Dreadnought Stanton, a New York Warlock as irresistible as he is insufferable. Newly engaged, she now must brave Dreadnought’s family and the magical elite of the nation’s wealthiest city. Not everyone is pleased with the impending nuptials, especially Emily’s future mother-in-law, a sociopathic socialite. But there are greater challenges still: confining couture, sinister Russian scientists, and a deathless Aztec goddess who dreams of plunging the world into apocalypse. With all they must confront, do Emily and Dreadnought have any hope of a happily-ever-after?
