An Island Strange and Wild by Lisa Amowitz

Live for today, before the island eats you alive…

When her fellow climate activist and secret crush dies unexpectedly, 18-year-old science prodigy Rosalie Gatell ditches her prestigious summer program for the remote, uncharted island where he was born. There, she discovers shocking secrets about her own past—and an island that defies the laws of nature, complete with a vanishing walled garden, a miraculous healing plant, and an unknown aunt trapped in a tree. But nothing confounds Rosalie as much as the enigmatic Liam, a reckless and beautiful island boy with a supernatural green thumb.
Falling for Liam is the worst idea imaginable, especially since he’s under a diabolical curse—but Rosalie can’t help herself. The closer she gets to unraveling his secrets and the island’s mysteries, the more she discovers that she possesses unexpected abilities of her own. But there’s no time to revel in her newfound magic. An ancient evil is stalking Salttain Island. And Rosalie will have to rely on her powers, instead of logic or science, to free Liam from his curse while keeping the corrosive threat from consuming her and everyone she’s ever loved.

Dive into this lush, haunting, romantic fantasy retelling of The Secret Garden, where no one is what they seem, and one wrong move can cost you your life.
