The Third Peregrination — Edward C. Patterson

The Jade Owl Legacy Series: Book 2 The world is on the brink, now that the relics flow together again. The new China Hands should have left the Jade Owl in the tomb, to fester silently for another age, but they didn't. Now there is a tapping in the basement and a flowering of new relics, all seeking to move Curator-General Rowden Gray and his crew into the field again to solve the mystery of The Seven Sisters. However, the world has changed since Rowden managed his first task. The new China Hands are sucked into the maelstrom of time, flowing together with the relics, now that the world is at the brink.
