Accidental Bonds by Marie Reynard

It was meant to be temporary. Fate had other ideas.
Victor Mills would do anything to protect his pack, even work with magic he detests. When the wards safeguarding his territory start to deteriorate, he’s forced to hire a local mage to fix them. He could tolerate the abrasive stench of sorcery, if only the mage didn’t also smell like everything his wolf has ever wanted.

Elijah Lauring has no intention of tying himself to a shifter pack; his neutrality pays the bills. Repairing the Mills pack wards should be a one-off job, but the spell he casts to tap into Victor’s energy stubbornly refuses to fade. The intoxicating connection that lingers between them plunges his magic into chaos right when he needs it the most.

As they grapple with their conflicting desires, they soon discover the wards aren’t the only thing decaying. An evil is infecting the pack land, and they must learn to trust each other and their growing bond to defeat it. If they fail, Victor’s pack will pay the ultimate price.
