Green Stone Ring (Forever Friends Book 1) by Karleen Staible

Gini, the gorgeous and passionate lobbyist for children, whom everyone loves. Franco, the rough-around-the-edges, big-hearted kid from the wrong side of the tracks. Ric, the quiet, lonely boy who becomes a swoon-worthy charmer. They grew up together, best friends.
What happens when Franco spends months away in China on business and Ric and Gini meet again? Far more than a love triangle, this book – the first in a three-book series – ventures deep into the human heart where commitment and character are tested. Are the bonds of friendship and love truly forever when it’s a matter of life or death?
