It might interest you to know of my novel – THE HADRIAN ENIGMA: A Forbidden History – has been recently published via Amazon.com (USA & UK) in both paperback & Kindle ebook formats. Though entirely fiction, it follows the historical record very closely, & weaves an account of the relationship of Hadrian & Antinous into an historical mystery/crime romance novel.
The novel is also available via Lulu.com (USA), Barnes&Noble, & The Book Depository UK, depending on where you live.
