For those of us with siblings, we all know that the relationships are anything but simple. Sometimes they’re great and sometimes they’re fraught with tension, but if you’re lucky, they’re the best friends you get to also be related to.

Here are my favorite books with sibling relationships that might not be perfect, but are precious and truly important.

1. The Cost of Knowing by Brittney Morris

From the acclaimed author of SLAY, comes a gripping, evocative novel about a Black teen who has the power to see into the future, whose life turns upside down when he foresees his younger brother’s imminent death.

2. Wings of Ebony by J. Elle

3. You’ll Miss Me When I’m Gone by Rachel Lynn Solomon

5. Love & Luck by Jenna Evans Welch

This book is both about mending sibling relationships and international romance, so this definitely on my list of books to read this summer.

8. Gemini by Sonya Mukherjee

Seventeen-year-old conjoined twins, Clara and Hailey are at a crossroads. Clara wants to stay close to home, avoid all attention, and study the night sky. Hailey wants to travel the world, learn from great artists, and dance with mysterious boys. This book is told in alternating perspectives and is such a heartwarming, unconventional story.

9. Summer Bird Blue by Akemi Dawn Bowman

This book shows us what it can be like dealing with the unthinkable—the sudden loss of a beloved sister. When Rumi’s sister Lea dies in a car crash, she has to process all the emotions that come with losing a sister that meant so much to her. You’ll need plenty of tissues for this one, but it is a heart-breakingly beautiful read.
