The Feast of Dead Man’s Hollow by Desirée M. Niccoli

It’s not like Theodore to risk his neck, but when a new commercial development project threatens his beloved bog, he sneaks onto the construction site to sabotage it, only to become mired in the very place he meant to save.
Ardruina’s not the rescuing type, but the clumsy man drowning in bog muck is only trying to help. Charmed by his good intentions and blustering flirtations, she wants more than an alliance. There’s only one problem—she harbors a dark secret and one wrong move could mean discovery. Saving the bog proves harder than expected, and Ardruina must choose between keeping her secret and saving Theodore’s life.
Before the day is over, heads will roll.
