I’ve occasionally gone on TV and movie fasts, usually to course-correct after overindulging in too many screen-based activities. But books are a constant and during no period of my life was I more immersed in books than as a teenager. “Young Adult” or YA fiction ruled my life, and it still does, sort of.

At the moment, no one is ruling my YA habit more than Jamaican-American author Nicola Yoon. I first heard of her in 2015, when a friend sighed like we were still 15 and told me to “just read it”. “It” was Yoon’s debut, the award-winning Everything, Everything,  the story of a sheltered 17-year-old named Madeline, whose life – and every single thing in it – changes when Olly moves in next door. Yoon was moved to write it after the birth of her daughter – and I don’t want to give anything away for late readers, but know this: the book is achingly romantic, joyous and thoughtful, and wears its heart firmly on its sleeve in the way familiar to anyone who was ever a teen. What’s more, it pulls off that rare thing in mainstream fiction: its heroine is part-black. (Yoon is a member of campaign organisation We Need Diverse Books.)

As a writer, her superpower is a sincerity that manages to remain unsentimental; it turns happy endings into something a little more bittersweet. I love it, and I am not alone: Everything, Everything will be on the big screen this summer, starring Amandla Stenberg.

Yoon’s second novel, The Sun Is Also A Star, came out last October, and was shortlisted for a National Book Award. If I had my way she’d write a book a year.
