I got hooked on this series very quickly in the first book; I just finished this series. Loved, loved, loved it! While the racers (mostly male but one woman as well) get all hot and sweaty in their cars, I was also feeling a bit hot under the collar. The heat isn’t just left on the racetrack. The couples burn up the sheets as well. The stories are hot, fun, and great page-turners. The interaction between this group of characters is flawless. The threads that tie the books together works perfectly. I highly recommend this series!
