Treasured by the Dragon

Dawn Chadwick never expected to spend an afternoon helping stage a children's play on dragon-shifter land, but her daughter Daisy has worn down her prejudices enough to volunteer. She's paired with Blake Whitby, a reclusive white dragon who prefers his lab to people but can't resist two meddling kids and their mother, even as a mate-claim frenzy pulls them together and Dawn's own family threatens to disown her for it. Tenth in the Stonefire Dragons series.
