Liliana's Invincible Summer is as captivating as it is heartbreaking. When the Mexican justice system fails to produce the file pertaining to Liliana's murder - let alone bring her killer to justice - Rivera Garza uncovers her long-dead sister's voice through letters, notes, journals, and testimonies of friends and family. The two sisters' voices become braided together in the process, speaking in a complicated tangle of love and grief. I constantly thought of my own sister, who is barely older than Liliana was, while I read this, and several times, I had to stop to cry. It's a haunting account of how intimate partner violence escalates, and how the signs are often missed by a society misogynistic and desperate to blame the victim. It surpasses Rivera Garza's goal, which was to recreate the missing file, by far - the detail and care put into this book is beyond what a coldly professional report could muster, of that I'm certain.
