Thawing Frost by J.L. Weil

The end is near. But will Olivia be able to save her dragons and the home she has come to love? Return to the Veil in the epic conclusion to the Dragon Descendants.
An unexpected reunion brings new possibilities to Olivia’s quest of finding the dragon stars. She and the four dragons travel to Iculon, a kingdom as cold and brutal as its heir. Olivia might have lost the Star of Fire to the witch Tianna, but she isn’t willing to give up. Not by a long shot.
Issik Westgard preferred a life of quiet and solitude until he met Olivia Campbell, the girl who found a way to thaw his frosty heart.
War threatens the Veil and all Olivia holds dear. She might not know what her future holds, but she’s willing to take the witch down with her to save the four dragons she loves. Piece by piece.
Four dragons.
One headstrong heroine.
And a reverse-harem fantasy romance that could change the fate of a dying race.
