The Problim children

"When the Problim children's ramshackle bungalow in the Swampy Woods goes kaboom, the seven siblings--each born on a different day of the week--have to move into their grandpa's bizarre old mansion in Lost Cove. No problem! ... But rumors about their family run rampant in the small town: tales of a bitter feud, a hidden treasure, and a certain kind of magic lingering in the halls of #7 Main Street. Their neighbors, the O'Pinions, will do anything to find the secrets lurking inside the Problim household--including sending the seven children to seven different houses on seven different continents"--Provided by publisher.
