After her grandmother Arlette's death, Betty is finally ready to begin her life. She had forfeited university, parties, boyfriends, summer jobs--all the usual preoccupations of a woman her age--in order to care for Arlette in their dilapidated, albeit charming home on the English island of Guernsey. Her will included a beneficiary unknown to Betty and her family, a woman named Clara Pickle who presumably could be found at a London address. Now, having landed on a rather shabby street corner in '90s Soho, Betty is determined to find the mysterious Clara. She's ready for whatever life has to throw her way. Or so she thinks...
