TITLE: The Memory Taker
GENRE: YA Magical Realism
Astrid takes memories. If someone can't cope with the loss of a friend or wife or someone they love, they can pay a fee and Astrid will erase that memory for them, relieving them of their unbearable pain. Astrid's younger sister is in a coma and Astrid has tried to get into her head to find the memory that has her so deep into unconsciousness, but it's too hard, too straining. But now she's found Kellan. He came to Astrid haunted by the murder of his girlfriend. And Astrid thinks that if she can help fill in the gaps of that horrific memory that's buried deep in Kellan's memories, she may find what she needs to save her sister.
Problem: I want the murder of Kellan's girlfriend to somehow be related to Astrid's sister, but I'm having trouble finding a way to plot it. I want it to be a twist that takes the reader by surprise at the end.
