He immigrated as a small child with his family as political refugees to escape the communist regime. Rehak grew up and was educated in Canada. After beginning university, his studies were quickly interrupted by failing health and a move back to Europe. His first novel, A Young Girl's Crimes, was initially started in several drafts while he was still a teen. Shortly after a rewrite and some cuts, it was successfully agented and published. Rehak was declared a literary prodigy by some and the book garnered much praise and criticism from prominent newspapers upon its publication and was even referred to by the Montreal Gazette as "The first Christian porn novel." The book then created heated debate both from a moral and literary standpoint, resulting in its being banned from some school library shelves.
