Lion's Legacy by L. C. Rosen

Seventeen-year-old Tennessee Russo’s life is imploding. His boyfriend has been cheating on him, and all his friends know about it. Worse, they expect him to just accept his ex’s new relationship and make nice. So when his father, a famous archaeologist and reality show celebrity whom he hasn’t seen in two years, shows up unexpectedly and offers to take him on an adventure, Tennessee only has a few choices:

1. Stay, mope, regret it forever.
2. Go, try to reconcile with Dad, become his sidekick again.
3. Go, but make it his adventure, and Dad will be the sidekick.

The object of his father’s latest quest, the Rings of the Sacred Band of Thebes, is too enticing to say no to. Finding artifacts related to the troop of ancient Greek soldiers, composed of one-hundred-and-fifty gay couples, means navigating ruins, deciphering ancient mysteries, and maybe meeting a cute boy.

But will his dad let Tennessee do the right thing with the rings if they find them? And what is the right thing? Who does queer history belong to?

Against the backdrop of a sunlit Greek landscape, author L. C. Rosen masterfully weaves together adventure, romance, and magic in a celebration of the power of claiming your queer legacy.
