Five Days in may

From Ninie Hammon, the sorceress of supernatural suspense comes Five Days in May, a tense, prophetic nightmare that will keep your eyes glued to the text through the very last page. Three members of the McIntosh family are setting appointments with death: Friday, May 10, 1963. That's the day an F5 tornado will rip across Oklahoma, obliterating everything in its path. Pastor Mac McIntosh lost his faith when his wife died - it's time to end the charade.
But when a mysterious inmate called Princess is set to be executed, he grudgingly agrees to meet with her in her final days. Princess has watched Mac and his family for years, looking out through someone else's eyes. She speaks to Mac's heart with insight and grace, while in her own heart she harbors a secret she's determined to carry to her grave about the little sister she confessed to beheading 14 years ago. Princess knows the monster tornado is coming.
She calls it The Big Ugly and she pleads with Mac to run! But by then, it's too late. For all of them.
