I'll Be There — Janet Woods

In the 'Swinging' 60s, Janey Renfrew goes to London. There, a group of friends encourage her to paint. She rises above the drug scene, until someone laces her drink and she learns that as a child she'd accused the wrong man of abuse. She intends to find some way to put things right, and Griff, her childhood friend, encourages her in that task as they fall in love. Women's Fiction by Janet Woods; originally published by Robert Hale [UK] as Against the Tide
