Comic superheroes such as Batman and Spiderman have a new rival - in the form of Britain's Prince William. During the busy preparations for Prince William and Kate Middleton's marriage, their love story is going to be published in the form of a graphic novel.

The royal romance between Prince William and Kate Middleton is being chronicled in a graphic novel due out in April, just before the couple gets married.

It's called "Kate and William: A Very Public Love Story", and it tells the story of a beautiful girl who goes to university and wins the heart of a handsome prince.

Cartoonist Mike Collins, working on the sketches from his studio in Cardiff, says Britain has a long tradition of romantic comics for girls, in which the female lead dreams of meeting someone famous and falling in love. He says the royal wedding is a real-life example of that.

Collins describes the royal couple as great fun to draw - Kate because of her flowing hair, and William because of his "classic" features.

Mike Collins, Cartoonist, said, "I think with her, it's her hair. She's got hair that's lovely to draw. It's always flipped back and flowing, it's fantastic. He's got this - and I never noticed until I started drawing him - a very classic face, very classic features. When he was at college he had this whole flick of hair, and I've been really enjoying sketching into that."
