This stellar debut about losing and finding family, forging unlikely friendships, and searching for answers to big questions will resonate with fans of Erin Entrada Kelly and Rebecca Stead. The only thing Rosalind Ling Geraghty loves more than watching NASA launches with her dad is building rockets with him. When he dies unexpectedly, all Ro has left of him is an unfinished model rocket they had been working on together. Benjamin Burns doesn't like science, but he can't get enough of Spacebound, a popular comic book series. When he finds a sketch that suggests that his dad created the comics, he's thrilled. Too bad his dad walked out years ago, and Benji has no way to contact him. Though Ro and Benji were only supposed to be science class partners, the pair become unlikely friends, and Ro even figures out a way to reunite Benji and his dad. But Benji hesitates, which infuriates Ro. Doesn't he realize how much Ro wishes she could be in his place? As the two face bullying, grief, and their own differences, Benji and Ro try to piece together clues to some of the biggest questions in the universe.

Thanks to her Ye-Ye's epic scavenger hunts, thirteen-year-old Ruby Chu knows San Francisco like the back of her hand. But after his death, she feels lost, and it seems like everyone--from her best friends to her older sister--is abandoning her. After Ruby gets in major trouble at school, her parents decide she has to spend the summer at a local senior center with her grandmother, Nai-Nai, and Nai-Nai's friends for company. When a new boy from Ruby's grade, Liam Yeung, starts showing up too, Ruby's humiliation is complete. But Nai-Nai, her friends, and Liam all surprise Ruby.

And alongside Nai-Nai, who is keeping a secret that threatens to change everything, Ruby retraces Ye-Ye's scavenger hunt maps in an attempt to find a way out of her grief--and maybe even find herself.
