Books with title The secret of the golden pavilion

A Hole Through Time? 22nd century technology in the wrong hands!? Something has gone terribly wrong at the 2134 global Caldwell Family reunion in Chicago. Caldwell cousins Delly, Zoe and Coco, were having a fantabulous time at the Caldwell Lake Michigan beach estate until they saw two of their favorite cousins fade into nothingness. Next, half of their enormous and powerful family disappears. Worse, the adults act as if the missing relatives never existed! What is happening? Do Nobel Prize hungry Uncle Taj and his new time travel machine have anything to do with it? Frightened but determined, Delly, Zoe and Coco know it's up to them to save their family members...and they have just 48 hours to do it. Mysterious golden rings reveal the secret to the disappearances. But, the only person who can make the family reappear is an ancient Igbo ancestor located in perilous 18th century Nigeria, where the Caldwell family began. Will the cousins' smarts, teamwork, and style be enough for Delly, Zoe and Coco to find a way back through time? The time-travel clock is ticking as they look for the one ancestor who can save them all.
