Once A Queen | Sarah Arthur

When fourteen-year-old Eva Joyce unexpectedly finds herself spending the summer at the mysterious manor house of the English grandmother she’s never met.
After strange things start happening in the gardens at night, Eva turns to the elderly housekeeper, gardener, and the gardener’s great-grandson, Frankie, for answers. Astonishingly, they all seem to believe the fairy tales are true—that portals to other worlds still exist. They suspect that Eva’s grandmother was once a queen in one of those worlds. 
But Eva's grandmother denies it all. After a horrific family tragedy when she was young, her heart is closed to the beauty and pain of her past. It’s up to Eva, with Frankie's help, to discover what really happened, whether family relationships can be restored, and if the portals are closed forever.
