Praise

"I cannot get enough from this incredible author! I have followed Shelby from CARROTS to this latest story and have loved every one. I couldn't say which I have liked and enjoyed more; Colleen is an incredibly talented person and her stories tell us why. This collection of stories starring Shelby Nichols is beyond good, and I highly recommend it."

– Christina Brett, Author

“Colleen Helme is one of the greatest authors working independently today.”

– Matthew LeDrew, Author

I've read thousands of books over my lifetime, several of which were excellent series, but I've got to say that reading this series has been the best EVER!!!!!! It's a good thing I'm retired now because I actually did not GET ANYTHING done while reading these books! No house cleaning, shopping trips, nothing except eating and taking care of my 8 cats and 2 dogs. Absolutely the PERFECT SERIES EVER!!!!
