Marius Gabriel was born in U.S.A.. He is a former Shakespearean scholar who left his academic pursuits to become a full-time writer. He says: "I have never trained as an artist. Mind you, I never trained as a writer, either. Also, like many self-taught persons, I had an idiot as a teacher. But onward and upward..."

In 1983, he published her first romance novels under the pseudonym Madeleine Ker, since then he became a popular Harlequin author. He also published some mystery novels under his real name. But, he has always been enchanted by art, especially computer graphics, and now he is decided to experiment new areas. He says: "I've made my living for the past 20 years as an author with a split personality. Recently I have been tempted away from thrillers and romances into the world of children's books (I have 3 kids under 10 years old). The first result was "Princess Smartypig," the tale of a genetically modified piglet"

Marius Gabriel lives in Spain with his wife and his three children.
