In the Anita Blake series the language of French is
spoken many times throughout. Jean-Claude is usually
the one that does seeing as how he's French and recently
Asher as well. Along the way, other characters chime in
also and here I have compiled the complete quotes in
French and explained their meaning for you.

ma petite
"my little one"

amante de moi
The Laughing Corpse page 194
"my lover", "my sweetheart", or "my mistress"

coquette
The Laughing Corpse page 201
It can mean "flirt" or "slut" but it's all in the way you say it.

je t'aime
Burnt Offerings page 160
"I love you."

C't'une bonne bourre.

It doesn't actually mean "a good lay" but more of "a good time" because 'c'est un bon coup' would be "She's a good fuck."
