After a mortifying incident in the school cafeteria, sixteen-year-old Mia is now standard on a battered sailboat with her family in the middle of the Caribbean. Her mom and dad believe that leaving everything behind is the best decision they’ve ever made, but Mia feels like she’s been kidnapped and imprisoned with no internet and no destination.

Her only hope is putting together a solar-powered satellite phone from scratch using salvaged parts so she can call her best friend and fix everything. By day, it’s island hopping. By night, Mia squeezes into a narrow bunk and talks to her imaginary friend, award-winning female scientist, Lene.

And then, two teenagers sail into Mia’s life, Alby and Nisha, promising friendship, and maybe even romance. Alby, who grew up in Australia, but now also sailing the world with his family, is thoughtful and kind. Nisha, who is vacationing on her dad’s megayacht and is bold and beautiful.

Now Mia has to decide to stay with her family or to go live with her Uncle in Tennessee.

I really enjoyed the writing and exploration of not only mental health with Mia’s mother and her OCD, but also Mia’s neurodivergence. To me, it was quite obvious that Mia was high(er) functioning autistic and I wish it was discussed or talked about more in the novel so readers could feel a bit more seen while reading. I think because of this, I was also reading Mia as younger than sixteen and felt more like she was thirteen/fourteen. 

But, overall, I really enjoyed this novel. The relationships felt authentic as well as the exploration of sexuality. Things felt evenly paced and realistic time wise. Oh – and there’s amazing representation of women in STEM. I think both teen and adult readers could enjoy this novel.
