Dark Ruby (Dark Jewels Trilogy)

For years, Lady Gwynn has kept the ultimate secret from her long-time love Trevin McBain after their singular night of forbidden passion--she has raised their son in the home of his long time enemy. But when the boy is suddenly accused of murder, Lady Gwynn will do anything to protect him, including marrying a scheming new suitor she does not love. Now only Trevin's return can save his son, rescue Gwynn from an unjust marriage, and rekindle their unbreakable bond of undying love. .
