When the World Grows Cold: Book 4, The Peaks Saga

Thirty Years Later...Ginna and Danny have been back from their time travels with Jon, Jale, and Martina for almost thirty years. Danny has settled into a normal twenty-first century life. But Ginna, nothing has been 'normal' since her return -- for she discovered she was pregnant, with no idea who could be the father of her child. Then Celestia, daughter of Jon and Martina, appears from the GAP, to take Ginna, and her daughter, Annemarie, to the future, hoping to help them find answers to their many questions. Book 4, The Peaks Saga

"...reads like the love child of Narnia's allegory and Dr. Who's spatiotemporal adventure with a delightfully original concept... of the mechanism of time travel and its consequences...a fun read and I recommend it for readers of post-apocalyptic fiction..." Elizabeth Rowe, The Cat That Reads, Book Reviewer
