The Penderwicks on Gardam Street by Jeanne Birdsall

The four Penderwick sisters are back at home in this endearing sequel. This time , though, the adventure is getting serious. woderful aunt Claire comes for a visit but offers the dreadful thought that it's time for the girl's widowed father to start dating! YIKES! One bad date and the horrible stoies of awful literary steip-mothers haunt the sisters until they decide this datin stuff must stop. An emergency MOPS (Meeting of the Penderwick Sisters) meeting must be held. The "Save-Daddy" plan is hatched and goes into action in true Penderwick fashion. That's to say elaborate plans are made but only partially fulfilled and it sort of end in a fun but silly mess.
