Johnnie Casanova — Jilly Cooper

At a friend's party, Richard falls desperately in love with the gorgeously naive Gemma. He is determined to treat her honourably. It's a pity the same can't be said for Richard's flatmate, the rakeishly sexy Johnnie, who also has his eye on Gemma. Gemma is dazzled by the attention, and quickly becomes besotted with Johnnie. So, Richard loves Gemma, Gemma loves Johnnie - and no one can quite work out exactly what Johnnie's intentions are.
