Hi Tina. Here is the order that they were written. I think they are best read in this order.
Stephanie Plum series;
One for the money
two for the dough
three to get deadly
four to score
high five
hot six
seven up
hard eight
to the nines
+(a holiday edition)Visions of sugar plums
She also has another totally different series; I've read the first one. It was good, but not as good as the stephanie plum series.IMO
full house
full tilt
full speed
