Usborne has signed a YA novel from Birkbeck creative writing MA alumni Sarah Alexander.
Fiction deputy director Anne Finnis acquired UK and Commonwealth rights from Hellie Ogden at Janklow & Nesbit UK, while US rights have sold to Houghton Mifflin Harcourt Books for Young Readers.
The novel, The Art of Not Breathing, follows a Scottish teenager who must face her family's tragic past as she investigates the mystery around her twin brother's drowning.
Finnis said: "Elsie feels so real, raw and haunted by tragedy. And I fell in love with the world of free diving that gives the story a wonderful extra dimension."
The book will be published in 2016.
