Fifteen year-old Valerie is used to losing things–she lost her dad to his job ages ago and her best friend moved with no warning...and hasn't been heard from since. During a weekend camping trip with her emotionally distant parents, she stumbles upon a hidden, mysterious stone and she finds herself desperate to keep it, to possess it. Two strange and beautiful boys have other plans, however. They follow her home–Leo, warm and seductive, who covets the stone and will stop at nothing to get it; and Noel, dark-haired and wise, who pledges to protect her and keep her safe.
As she delves deeper into the magic of the stone and the Celtic lore that surrounds it, Valerie realizes that she's losing. Again. But this loss might involve more than a magical stone – this time, she just might lose her heart.
