Fangirl by Rainbow Rowell @amys_smile / Via instagram.com Fangirl is about sisters growing apart, and how one girl specifically carves out her own space in a world she used to share with her twin. Cath and Wren grew up obsessed with the Simon Snow series — diving into forums, writing fan fiction, dressing up in costumes for the midnight premieres — but now that they're starting college, Wren has moved away from the fandom and from Cath. How will Cath figure freshman year out without her partner at her side? 3. Atlas of Unknowns by Tania James Simon and Schuster Linno and Anju, the sisters of Atlas of Unknowns, spend their lives reaching out for each other — over the wound of their mother's mysterious death, which left them in the care of their ailing father and superstitious grandmother; across the miles that separate them when Anju travels to the U.S. on a prestigious scholarship; even (and especially) when Anju drops out and runs away to Queens, leaving Linno on the other side of the world trying to find her. Theirs is a story about the independence of striking out on your own, the comfort in settling into a home, and the struggle of being pulled in both directions. 4.

I'll Give You The Sun by Jandy Nelson @booked_out / Via instagram.com I'll Give You The Sun alternates between the perspective of Noah at 13 years old — when he and his twin sister Jude are incredibly close — and Jude at 16, when the two are barely even speaking.

The Blind Assassin by Margaret Atwood @tiffanierdevos / Via instagram.com There are three stories at play in Margaret Atwood's dreamy novel — the elderly Iris Chase's recollection of her life growing up around World War II, the novel her sister wrote before killing herself, and the science fiction tale the characters within that novel tell each other. But at its core, The Blind Assassin is about two sisters: one who worked through her demons by writing until she reached a point when she couldn't go on any longer, and the other trying to understand how she got there. 8.

Mambo in Chinatown by Jean Kwok Riverhead Mambo in Chinatown is a sweet story that will ring true to anyone who's felt the complicated pull of familial obligations.

Housekeeping by Marilynne Robinson @msstreeturchinvintage / Via instagram.com After losing their mother, sisters Ruth and Lucille live through a cycle of caregivers — first their grandmother, then a couple of ill-equipped great-aunts, and finally, their eccentric aunt Silvie.

How the Garcia Girls Lost Their Accents by Julia Alvarez @carolingkats / Via instagram.com The four Garcia sisters navigate a new world at the same time when they have to leave their home in the Dominican Republic for New York City.

Shanghai Girls by Lisa See @ellenagogo / Via instagram.com The sisters of Shanghai Girls — 21-year-old Pearl and the younger May — see their complicated relationship tested when their father, drowning in debt, sells them off as wives to Los Angeles suitors.

Code Name Verity by Elizabeth Wein @vixenomous_reads / Via instagram.com The heroes of Code Name Verity aren't sisters, but their bond is as strong, selfless, and loyal as any could be — unsurprisingly, since they meet as pilot and spy fighting for Great Britain in World War II. When their plane crashes, and the spy (code name: Verity) is captured and detained by Nazi authorities, she's forced to detail her confessions — which she does in the form of a novel — while, elsewhere, Kittyhawk plots her rescue. 15. Kira-Kira by Cynthia Kadohata @nehareads / Via instagram.com You'll find Kira-Kira — named after the Japanese phrase Katie Takeshima's big sister teaches her, meaning "glittering" — in the young readers' section, but anyone with a heart will enjoy this deeply moving story about a Japanese-American family who moves to Georgia in the 1960s, and the ways in which Katie is cared for, and disappointed by, her sister. 16. Little Women by Louisa May Alcott @house_eightytwo / Via instagram.com The March sisters are classic for a reason — their heartwarming story about surviving without their father and with little money during the Civil War is one of courage, perseverance, selflessness, and the impenetrable bonds among family.
