Broken - Bound by Magic, #2

They were fated to be together. .but she wanted out, and did anything she could to be free. Now we're all paying the price. Their broken bond is still hurting him, even though they're no longer together. What's even scarier is that none of the doctors in town can help us. Nothing like this has ever happened before in Atlantis. The best way to figure out how to help him, they say, is to go back to the source of the magic that broke Matt and Sarah apart. If only it was that easy. No one's seen Sarah in a while.
Matt is too heartbroken to even think about her. But he's also getting worse. She's all we've got. We'll have to get past what happened before in order to find her. Then, to save someone from magic no one's ever seen before, I'll have to do something no one's ever done before: split my soul. Let's just pray it's not too late to save Matt from dying.
