Laird of Misrule by Mary Wine

The Midnight Well was fabled to be enchanted.

Tonight, Dugan planned to make sure the little lass venturing out to peek at her future got what she was looking for.
One moonlit encounter. That was all it might ever be, and yet, Dugan discovered he craved more. Much more.
At the end of the harvest, Samhain bonfires had been held under the moon for as long as anyone remembered. Were they sinful? Perhaps. But they were fun, and Dugan intended to give himself another chance to see the lass he’d encountered at the well.
Tonight though, he’d go so far as becoming the Laird of Misrule. The position came with a very pretty queen consort while the bonfire blazed.
