The Bold Warrior - Parallel Society, #6

The Parallel Society has a singular task - to protect the universe from the troubles caused by other universes intersecting with ours. But recent disruptions to the Society have place Veronica "Roni" Rider in the position of team leader, and they don't have time for her to get acclimated. Especially when one of their own goes missing. Now, it's up to the remaining members to find their lost teammate, uncover what really happened, and set things straight.
Of course, it'll be far more difficult than that. And when their nemesis Yal-hara appears, it might be downright impossible.
