Here is a complete list of the Wildflower series by V.C. Andrews.  You will first see a list of all the titles.  Then you can read what the book is about.  If I have posted a review of the book, i will include that link also.

1. Misty
2. Star
3. Jade
4. Cat
5. Into the Garden
6. Wildflowers (All four stories together)

1.  Misty

All Misty ever wanted was a normal family. But like so many others, Misty's parents didn't stay together. Now they use Misty to hurt each other, to deliver tiny cruelities in an endless stream. Misty knows her might love her. But Misty has an unspeakable secret that burns in the core of her very being: she hates them.
Misty isn't as alone as she thinks. She's just about to meet three other girls who are just like her--each one with their own dark secrets to share...

2.  Star

"It would be a cold day in hell before I could ever forgive my parents."  Star hides her pain, like the other girls in the therapy group that's supposed to help them.  But she knows how she feels deep in her heart.  Even though her mother and father are still alive, they are dead to her.  Today, it is her turn to reveal her secrets.  Star will tell her story to Doctor Marlowe and the others, and she will finially face the dark nightmares of her past...

3.  Jade

Jade had listened to Misty and Star tell their stories. Now it is her time to speak. But she can't. For while the others in Dr. Marlowe's therapy group had exposed their hidden pains and secret pasts, they are nothing like Jade. They don't know what it is like to be a pawn in a courtroom battle too hateful to ever forgive.
Or that escaping the madness had lured Jade into an ordeal too traumatic to forget...

4.  Cat

Cat had listened patiently as the other three girls in Dr. Marlowe's therapy group shared their innermost feelings. They had described their broken families honestly, to the point of pain. If cat doesn't tell her own tale, the others will see it as a betrayal. So she has no choice.
Or does she? Maybe she could lie--just make something up. Anything would be better than the truth. For Cat has the darkest, most horrifying secret of them all...
