The Seas of Distant Stars — Francesca G. Varela

Agapanthus was kidnapped when she was only two years old, but she doesn't remember it. In fact, she doesn't remember her home planet at all. All she knows is Deeyae, the land of two suns; the land of great, red waters. Her foster-family cares for her, and at first that's enough. But, as she grows older, Agapanthus is bothered by the differences between them. As an Exchanger, she's frail and tall, not short and strong. And, even though she was raised Deeyan, she certainly isn't treated like one. One day, an Exchanger boy completes the Deeyan rite-of-passage, and Agapanthus is inspired to try the same. But, when she teams up with him, her quest to become Deeyan transforms into her quest to find the truth―of who she is, and of which star she belongs to.
