When Yseult Urquhart's magic finally manifests, she finds herself saving her own life and faced with a choice.

Submitting to her family's demands that she returns to Scotland and joins Avalon Hall - a school for witches who come late into their magic - the youngest member of the powerful Urquhart clan enters a place of mysteries and secrets, where nothing is what it seems.

Voices from the past, visions of long ago times, even a possible ghost, all materialise before Yseult's eyes and ears, driving her to a spiral of confusion and curiosity that has her delving into what lies behind Avalon Hall.

And why does it carry that name?
