2019 Winner for the YARWA’s Athena Award for Excellence in Young Adult & New Adult Fiction in the YA/NA Speculative Category

Hana isn’t supposed to exist. She’s grown up hidden by her mother in a secret room of the bioship Cyclo until the day her mother is simply gone—along with the entire crew. Cyclo tells her she was abandoned, but she’s certain her mother wouldn't leave her there to die. And Hana isn’t ready to die yet. She’s never really had a chance to live.

Fenn is supposed to die. He and a crew of hired mercenaries are there to monitor Cyclo as she expires, and the payment for the suicide mission will mean Fenn's sister is able to live. But when he meets Hana, he’s not sure how to save them both.

As Cyclo grows sicker by the day, they unearth more secrets about the ship and the crew. But the more time they spend together, the more Hana and Fenn realize that falling for each other is what could ultimately kill them both.


Hauntingly beautiful, completely absorbing, this book will linger with you long after the final page. Toxic asks intricate questions about the identities we inherit and the identities we create, and the sacrifices we're prepared to make for both. Lydia Kang took my breath away.” – New York Times bestselling author, Amie Kaufman

Fenn & Hanna
Their relationship moved pretty quick, but considering they're in a life or death situation I suppose.../>

By Carrie October 17, 2018

Toxic by Lydia Kang is a young adult standalone romantic science fiction fantasy read that has maybe just a touch of horror to it too. When finished with this one it was one of those wow, I didn’t expect THAT moments, but in a good way of course.

When you read the blurb for Toxic, you immediately recognise the power and potential of the story. And I think it's safe to say that it delivered on all accounts.

"I slumber next to a boy who first saw me as an impediment, who taught me how to fall in love in low gravity."

I didn't think I could feel...
