   Summary

   Zayne has always been unnaturally attached to the Xia siblings, but one night when he witnesses their terrible secret his true feelings are exposed. A supernatural dream causes him to switch bodies with Caleb's sister to indulge in his deepest fantasy.

   "It wasn't that Zayne wanted to break their bond and attach them to himself. What he desired was to be absorbed into it."
