It's been three years since the Virgil County High School Massacre. Three years since my best friend, Sarah, was killed in a bathroom stall during the mass shooting. Everyone knows Sarah's story--that she died proclaiming her faith.

But it's not true.

I know because I was with her when she died. I didn't say anything then, and people got hurt because of it. Now Sarah's parents are publishing a book about her, so this might be my last chance to set the record straight . . . but I'm not the only survivor with a story to tell about what did--and didn't--happen that day.

Except Sarah's martyrdom is important to a lot of people, people who don't take kindly to what I'm trying to do. And the more I learn, the less certain I am about what's right. I don't know what will be worse: the guilt of staying silent or the consequences of speaking up . . .

Hadley is angry about a lot of things: Her mom going to jail. Having to move to another state to live with her older sister, Beth, even though they haven't spoken in five years. Leaving her friends and her school behind. And going blind.

But then Hadley meets Lila.

Lila is an abandoned dog who spends her days just quietly lying around at the local dog rescue where Beth works. She doesn't listen to directions or play with the other dogs or show any interest in people. So when Lila comes and sits by Hadley (which is hardly anything, but it's more than she's done with others), Beth thinks maybe Hadley can help Lila. She tells Hadley they'll bring Lila home as a foster dog and Hadley can teach her to follow commands, walk on a leash, and be more of a people dog so she's ready to be adopted.

Only working with Lila is harder than Hadley thought, and so is the mobility training she starts taking to help with her failing vision. It feels like Lila is too stubborn to train and that learning to use a cane is impossible. But unless Hadley can help Lila, she'll never be adopted into a home. If Hadley could just let go of her anger, she might be able to save Lila ... and herself.
