Reindeer Runes is the second in the Winter Witches of Holiday Haven series, but it stands alone. It's written by a different author and features different characters, but takes place in the same world.
Rudolph and Jack Frost are missing! In this fun Christmas cozy mystery Lumi and Corbin, Jack Frost’s brother, must find the missing icons before Santa finds out Rudolph is missing and before Jack misses his coronation as the Frost king. Lumi and Corbin are likable and their interactions feel real. Corbin is powerful but funny and a good detecting partner for Lumi, who is smart and quiet, and laid back. Their blossoming attraction didn't feel forced or overly rushed.
The mystery was well-done. We had several possibilities and the "deadline" added some urgency. The supporting cast is a colorful collection, including pixies.
With mystery, magic, and a bit of romance this book is a perfect read for this time of year.
