Silver Rose

Alsmora: A land of magic, adventure, and myths turned reality.
Sixteen-year-old Penelope Bogg is a handmaiden to the Queen of Alsmora, but she is anything but a simple servant. Here are just a few things on her mind:
Her mother's mysterious death two years previously;
The fact that she never inherited her magic by the age of thirteen;
The strange, cloaked girl following her through town, muttering that Penelope is "the right descendant"; and
The little problem of her collapsing when her vision changes to silver.
Soon she learns the truth: her collapses are a warning. A dark shadow is looming over the kingdom of Alsmora and she and her new friends, Mag and Artie, are the key to saving everyone.
The reason: Penelope Bogg is a witch.
