The Heart of the Lost Star by Megan Derr

Kamir is on the verge of losing everything. Knowing full well he can’t meet the ultimatum his parents have issued, he instead finally puts in motion his plans to live completely independent of them. His plans are interrupted, however, by the unexpected return of his despised ex-husband—and thrown even further into upheaval when he ends up comforting the man he’s secretly loved for years.

Jader may not know where he comes from, but he knows where he belongs and what he wants—until he helps rescue some stranded Bentan travelers, one of whom look almost exactly like Jader, throwing his life and everything he thought he knew into tumult. Scared and overwhelmed, Jader flees—and lands unexpectedly in the arms of a man he’s always seen, but never really noticed.
