A lifelong student, I am currently on hiatus from the PhD program at the U of Memphis and will begin to write my 2nd book this spring. I have an AS in Biology, a BA and an MA in English Lit. Plus I began a degree in Geology while living in CA. I live with the love of my life, Sissy, a Chihuahua, Joey, and Alero, my ThunderCats, who help me cope with narcolepsy.
