Shrouded - Heartstone, #1

Dolfan believed in the Heart... until it gave her to another man. When Vashia arrives on Shroud as an indentured bride, Dolfan recognizes immediately that they are meant to be together. Broken, lost, and on the run, she trusts no one, but Dolfan has enough faith for the both of them... Until his people's sacred ritual gives Vashia to someone else. Until Dolfan's faith, and his heart are tested. Vashia's arrival ignites a storm on Shroud, and the full-scale invasion that chases after her threatens to destroy Dolfan's home, his culture, and his planet.
If he can't challenge his own beliefs enough to admit the ritual was wrong, the only woman he wants will likely be the end of everything he's ever known.
