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, Valerie stumbles upon a hidden, mysterious stone and she finds herself compelled to keep it, to possess it. Two enigmatic, beautiful strangers, however, are also interested in the stone. 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 both her and the stone safe. As she delves deeper into the magic of the stone and the Celtic lore that surrounds it, Valerie realizes that she's in danger of losing. Again. But this loss might be her biggest of all because it involves more than a magical stone - this time, she might lose her heart.
