Adin is a former vampire who lives with Celia and has a wild crush on his best friend Jackson who is a wizard (and carpenter). At his birthday he comes on to Jackson for a menage but is rebuffed. After talking to Celia she tells him to head to Jackson's and just fuck him and get it out of his system if that's what he needs. So he does. And it's smokin'. The book is basically Jackson and Adin working through their feelings for each other and feeling each other up over a weekend. You really got the sense of the connection between Adin and Jackson, not so much Adin and Celia but maybe that's cause there was no m/f smexin' on screen. She's pretty open about Adin admitting he's in love with Jackson too and being okay with them having the occassional weekend fling and I know where this goes down the road but I'm ready to ditch her. I think there maybe have been m/f books before this? Not sure. Anyway, amazing chemistry between the two guys and I'm looking forward to books 2 and 3 in the series.
