Blue Steel Chain (Trowchester Blues #3) by Alex Beecroft

At sixteen, Aidan Swift was swept off his feet by a rich older man who promised to take care of him for the rest of his life. But eight years later, his sugar daddy has turned from a prince into a beast. Trapped and terrified, Aidan snatches an hour’s respite at the Trowchester Museum.

Local archaeologist James Summers is in a failing long distance relationship with a rock star, and Aidan—nervous, bruised, and clearly in need of a champion—brings out all his white knight tendencies. When everything falls apart for Aidan, James saves him from certain death . . . and discovers a skeleton of another boy who wasn’t so lucky.

As Aidan recovers, James falls desperately in love. But though Aidan acts like an adoring boyfriend, he doesn’t seem to feel any sexual attraction at all. Meanwhile there are two angry exes on the horizon, one coming after them with the press and the other with a butcher’s knife. To be together, Aidan and James must conquer death, sex, and everyone’s preconceptions about the right way to love—even their own.

Well. this was a first,  my first asexual main character.  Back in my day we just called it conceited, but oh well we'll stick with asexual.  I really did not warm up to either characters in this book,  the story line was good, the writing and flow was good, I think just Aidan's attitude maybe put me off.  Some abuse scenes maybe a trigger for some readers, be advised
