( EW.com ) -- Is this the face of a beautiful prima ballerina who burns for her beautiful brother — and yearns for revenge against her equally beautiful mother ? Lifetime thinks so . EW can confirm that 26-year-old Rose McIver will star as Cathy in `` Petals on the Wind , '' the network 's upcoming sequel to its hit adaptation of V.C . Andrews 's `` Flowers in the Attic . '' McIver will inherit the role from Kiernan Shipka , who played Cathy from ages 12 through 15 in the first film . The novel on which Petals is based picks up immediately where Flowers leaves off , covering a sequence of events that take place over the course of 12 years ; Lifetime 's movie version will take a different approach , beginning a decade after the events of the first movie . ( Which is a good thing , since it means viewers will be spared scenes of Sally Draper seducing a 40-year-old man . ) McIver , a New Zealand native , may be known best to American audiences as Vivian Scully on Showtime 's `` Masters of Sex '' or Tinker Bell on ABC 's `` Once Upon a Time . '' As her Facebook page notes , McIver also used to study ballet and jazz dance — which may come in handy when playing dancer-turned-teacher Cathy . She joins returning `` Flowers '' cast members Heather Graham and Ellen Burstyn , who will reprise their roles Cathy 's wicked mother and grandmother , respectively .
