I don't tend to get into stories where one of the main characters realizes he's gay as an adult, but this did work for me. What always helps is that both characters are hot, of course. Jeremy, the police officer (visions of him on his motor bike are priceless) has always dated women, but never felt that zing. Rafe is a private detective he contacts to help find a missing young lady who's also a family friend. One of the things I did appreciate was that Jeremy remembered Rafe from a previous case, but the author didn't do anything as cliche as "love at first sight" thing from that previous meeting. Too many of those M/M romance gizmos really get to me.
The plot was well-developed, as well as, the confusions surrounding Jeremy's struggles to come to terms with the way he's feeling towards Rafe. Also, nice were the secondary supporting characters. The author used them to show the dynamics of both supporting, rejecting, and not-really-ready-to-coping views of the gay lifestyle. I find normally while reading of such characters as Jeremy, that I tend to roll my eyes at some excerpts, but he comes off as very endearing. I couldn't help but be drawn towards him. Rafe had some issues with which he had to struggle, but he was also not your typical gay PI character either. I guess that's what I appreciated the most from the writing is that I felt these guys were different from the norm.
Last, but not least, the plot of the disappearance slowly did reveal itself quite nicely and was interwoven with the character development. Unlike the usual M/M romance/mystery/investigation story, you don't get the sense that either the romance or the investigation were treated as secondary fillers to meet some page quota.
In all this really worked for me and I loved it.
