Many of her books had an abusive dad or stepdad figure in them, I think that was Jacqueline writing on a topic she knew well, considering she mentions in her interviews that she had a scary dad. Off th e top of my head I can think of several with abusive dads ,stepdads, neglectful mums or other caregivers who were abusive
Cookie (domestic abuse)
Lola rose (ditto)
Secrets (also an emotionally invalidating and neglectful mother for the rich girl)
Clean Break
The Bed and Breakfast Star (Macks treatment of elsa would be considered abuse now, I say probably normal for early 90s but still could have had an effect. I couldn't see an adult Elsa wanting much to do with Mack unless things changed in the interim.)
Waiting for the Sky to Fall (father overbearing but also quite scary, bad temper, lashes out at mother for being fat, and also Katherine sister Nicola. Katherine is put under lots of pressure for being gifted and even considers suicide over fear of exam failure )
Deep Blue (emotionally abusive dad, another gifted child put under extreme pressure )
Nobody's Perfect (sandras boyfriend Michael has a bullying dad. Sandra herself mentions a brief stay in care where she was smacked for refusing her milk and wetting her bed)
The Story of Tracy Beake r mentions an abusive stepfather figure leading up to her being taken into care
Amber (Amber mother Jay raised by abusive nuns)
The Illustrated Mum (Marigold raised by abusive nuns)
The Other Side (mother not abusive as such but severely depressed, father and stepmother not cruel as such but don't understand Alison. But I think typical of 80s parenting back then. Mental health in kids just wasn't recognised except in cases where the child acted out very badly it seems, quiet kids were left to get on with it)
Falling Apart (more emotional neglect invalidation of a bereaved child)
Love Lessons (sexual grooming, blamed for it)
The Power of The Shade (inappropriate teacher and pupil relationship )
Wave Me Goodbye (teenager humiliated for wetting bed)
Ellie's father in the Girls series is a bit of a See You Next Tuesday calling Ellie's art "twee"
