Devastated by the freak death of her fellow climate activist and best friend/secret crush Tyler, eighteen-year-old science geek Rosalie Gatell decides to ditch her prestigious summer study abroad and escape to the place of his birth, which happens to be an endangered and uncharted island off the coast of Maine. Once there, Rosalie discovers a shocking truth about her past...and that what troubles this island goes far beyond the laws of nature. Even with a vanishing walled garden, a miraculous healing plant with a mind of its own, an unknown aunt trapped in a tree, nothing confounds Rosalie as much as the enigmatic Liam, a reckless and beautiful island boy with a supernatural green thumb.Rosalie believes she may have found salvation in this island wonderland-and a path to completing Tyler's climate work. But as her attraction to Liam grows, she's confronted by myths and legends about her family's origins that forces her to reconcile science and magic in order to save the island, and everyone on it, from an ancient evil. To do so, Rosalie will have to rely on her own power, instead of logic or science, if she is to free Liam from his curse while keeping the evil from consuming her and everyone else she's ever loved.
