Jade's Choice. The Crystal Warriors, #3

A talented young artist whose dreams have been crushed... A crystal warrior who'd rather die than be condemned again.... Jade's so desperate to provide for her chronically ill sister that she decides to sell herself. Her first "client" locks her in a motel room with Malach, the Crystal Warrior destined to be her life-mate. Malach is a complex, compelling man, and he soon captures Jade's heart. But Malach has a dark secret: He plans to kill himself rather than risk being imprisoned in his cursed crystal a third time.
And saving him could be a losing battle... because he's still in love with the woman who refused to bond with him decades ago.
