Pieces of me by Amber Kizer

When high school oddball and introvert Jessica Chai is killed in a car accident, her parents decide that Jessica would have wanted her organs donated to those who so desperately need these gifts of life. But Jessica is angry about dying and being dismembered. Taking the idea of cell memory to the next level, not only do the recipients get pieces of Jessica, but gets pieces of their memories and lives moving forward—she knows what they know and keeps tabs on their growth, recovery, and development. This begins her journey to learn her purpose as she begins to grasp that her ties to these teenagers goes beyond random weirdness. It's through their lives that Jessica learns about herself, as she watches the lives she literally touched continue to interlock

Amber Kizer is not one of those authors who wrote complete books at the age of three and always knew she wanted to be a writer. When she faced a rare chronic pain disorder her freshman year of college, she knew she was going to have to learn to live outside the box. After one writing workshop, she fell in love with telling stores and she’s still going strong. Her characters tend to be opinionated, outspoken, and stubborn—she has no idea where that comes from. 

A food lover, she plans trips around menus, wishes cookbooks were scratch and sniff, and loves to make complicated recipes—especially desserts. When she’s not reading from a huge stack, she’s coaxing rose bushes to bloom, watching delightful teen angst on television, or quilting with more joy than skill. She takes her tea black, her custard frozen, and her men witty. She lives in the Seattle area with a menagerie of animals that seems ever changing.
