First of all, I'll just say that you have to take the attitude of "this could never happen in real life" before even beginning this book. After all, the entire book (apart from the epilogue) happened in less than 48 hours. The couple met, fell in love, and became engaged.
This fast-paced, non-boring story started when Nicki saw a man dressed in a tux standing outside her door. In a daze, she thought she was imagining things, but reality soon hit her when she figured out the man was playing chauffeur for Nicki's long lost mother. Nicki is instantly attracted to Garrett Hamilton, but appalled that her mother would show up after all these years.
Throw it a lot more drama: Garrett's cousin wedding in Vegas, Reno's return, he mother's revealing the truth and re-starting an old tradition, and the hilarious assumption that Garrett had ridden into town and was planning on marrying Nicki, and you have an interesting book. Reading this, I knew it was just a story ant that's okay. After all, there's always something magical about Dry Creek!
