the grimmelings by rachael king
You must always be careful what you wish for…
Ella knows that words are powerful. So she should have known better than to utter a wish and a curse on the same day. That evening Josh Underhill goes missing, and a mysterious horse appears on the hill above her house. A new boy appears as well, seemingly in answer to her wish.
Who is Gus, with his impish grin and quick temper, who seems to know more about her family that he should? And what does the black horse want?
Ella soon finds that her grandmother’s warnings of dangerous lake-dwelling creatures are more than just folk stories. Along with her loyal pony, Magpie, she must unravel the mysery and break an old curse. Can they save not only her family, but the entire community?
