A pretty solid book for upper elementary/ middle schoolers, and honestly it was soo well written and creepy, that I think this absolutely could be adapted into a creepy as hell adult horror book. Two Irish orphans find themselves in an isolated crumbling down house working for a sick family. They're not technically getting paid but at least they have a place to stay and food to eat. While working at this remote house, Molly and her younger brother, Kip, begin to realize that something is horribly wrong. Someone is breaking in at night, everyone has nightmares, and they're all slowly getting sicker. Plus, the tree next to the house is menacing AF. Slowly they learn about the ominous night gardener and realize that sometimes the scariest stories are the true ones, ones that you keep yourself from believing. Genuinely creepy at parts, this book will attract a variety of readers.
