In Case of Emergency by Courtney Moreno
Moreno's debut novel is absolutely stunning. Protagonist Piper Gallagher is an EMT driver living in Los Angeles, and violence is a normal part of her day. Her attempts to grapple with this while running from the demons of her past creates a striking and realistic portrayal of the complexity of trauma. This book will haunt you, and poke you in the places you feel most human.
