Fire and Tears: Series Collection Books 1-3. Fire and Tears

In a city wracked by a magical war, where allies have become enemies, three couples confront a devastating choice between duty and love. Layla Brightarrow has loved the elven lord Ulric for years, but when the sorcerers invade, and the elves choose neutrality over helping their human neighbors, Layla is forced to leave her longings in the past. Until Ulric returns with seduction on his mind. But trust is impossible when she's charged with killing his brother. Nuala's unique magical skills have kept her confined to the elven city and separated from the man she loves for centuries.
But when Einar is sent to accompany her into the neighboring human city, their passion reignites. And Nuala knows that hunger could cost them their lives. Mina Dawnswealth lost everything to the war. Her hate for the elves rivals her hate for the sorcerers who invaded her city. So when she's charged with accompanying the elven lord Althir on a secret mission, the last thing she expects is a desire so tempting she must question everything she's known. Giving in to their longings could cost them all they hold dear.
Where life and death reign, temptation can kill. But in the end, love may be their only salvation.
