Narcissus (Challenged by Love #2)
Autumn Montague

Widower Alasdair Hedgeford was not oblivious to Julian’s desire, but married to Julian's sister, his place in the lad's life was as older brother. No more. Over the years, he's done his best to show Julian affection, but that affection has changed into a desire for more.
Yielding to that desire would mean breaking two taboos. But given the opportunity to to visit Julian for the annual "First Foot" celebration, Alasdair cannot help but extend a challenge to the man: "Come dine with me tomorrow night, to celebrate the New Year."
