Starcrossed
(Book)

She was made of blood and bones, and he was made of space and stars. Back in a time when there were still students of the stars, there were two friends, Acamar and Eridani. Eridani was a star pupil studying the night skies, and Acamar . . . well, he was made of the stuff she studied. In a star-crossed twist of fate, these long-distance friends find they’ve wished themselves into unexpected new worlds. Filled with stardust and moonglow, this cosmic adventure shows us how even the most brilliant wishes can have a mind of their own—and that true friendship can endure, despite time and space. -- from Amazon.
