Montana Sky World Harper Ranch Series Continues

Book two in the Harper Ranch Series is now available!

Almost a year from book one’s audio release, I’m so excited to announce the series continues with Rebel Love Song! It is an honor to be the narrator for this series of sisters who risk everything to homestead the Montana territory and give their hearts to worthy (and handsome) men.

Gorgeous twenty-year-old Jessamine Harper faces the retribution of an angry government bent on stopping her suffrage writings. The rugged Bethesda Janes, a metalsmith hiding his Jewish heritage and his heartbreaking past, falls in love with the beauty, intelligence, and caring heart he finds in Jess. From urban St. Louis to the prairie and mountains of 1887 Montana Territory, intrigue, jealousy, and ambition bring Jess, Bethesda, and a determined government agent to a dramatic stand-off.

Ms. Nelson’s writing has an elegance that compelled me to turn the pages long into the night,” writes Linda N. Pines, EreaderNewsToday (4.9 out of 5 stars for Book One in the series, Rye’s Reprieve).

Now the adventure and romance continue with the trials and triumphs of Jessamine, the tomboyish, activist middle Harper sister, in Rebel Love Song.

Undiscovered Country: A Spiritual Adventure by Kathryn Hulme – Narrated by Mary Castillo

A chance encounter with a spiritual master in a Paris cafe, radically changed the trajectory of the life of author Kathryn Hulme.

Best-selling author, world traveler, humanitarian and spiritual seeker, Hulme lived and loved with a courage that defied the age. Long out of print and forgotten, her memoir is now available in audio, print and ebook.

Undiscovered Country is a tribute to Gurdjieff and his teachings, a vivid personal memoir of her experience as his student, and of the burning spiritual intensity that dominated her life as a result of his unflinching guidance and fatherly love.

She did it! New mystery now on Audible







The first thing you should know is: I did it.

The moment I read the opening line to Stardusted: A Frankie Franklin Mystery, I was in! Ever since my grandma introduced to classic movies starring Myrna Loy,  Jean Harlow, Olivia de Havilland, Errol Flynn and Clark Gable, I’ve had a thing for old Hollywood. In this cozy comedic mystery set in the 1930s, I got to be the voice of America’s Kid Sister, Frankie Franklin who holds the smoking gun in a terrible on-set prank, or attempted murder…
