Query: What if...

N. J. Sparks has written a thoroughly comprehensive guide to "what if." What if terrorists succeed, on our own soil? What if we build a bomb shelter in the backyard? What if the unthinkable actually came to pass? This novel is much more than a how-to, however. Ms. Sparks has written an intense, believable, and thrilling story that will leave you breathless. Caley Wells' vision of building her own bomb shelter in case of nuclear, chemical or biological attack takes you on a ride examining big government, property rights, and what it means to be an American. Set in the high desert landscape of Arizona, Ms. Sparks uses vivid imagery to paint a picture of American life resplendent with family, horses and love that is threatened beyond her characters' will to survive. Educational, enlightening, and lucid, you will be asking yourself "what if" long after the last page is turned.Lynda HalesAuthor of TREACHEROUS LOVE, Spring 2005
