Storyverse and the Return of Shakespeare. STORYVERSE, #3

The second Shakespearean war has come and the dangerous forbidden lord Abigail Shakespeare is back and ready to conquer the Storyverse. First she needs to retake her old hideout, now the Storyverse School, putting thousands of kids in the firing line. Winning the war means recovering the powerful Ring of Everything she secreted on the school grounds, and she'll stop at nothing to get it. Tessa Storm's life has been thrown upside down.
Her best friend's mother has been possessed, a bratty classmate is acting strangely, and her friend William is manifesting mysterious powers of rage and flame. Worse, she's just stumbled over a secret which might get her murdered!  Dark powers are gathering and taking advantage of every mistake, leaving Tessa and her friends to rely on their training, their powers, and the quick wits. Graduating will mean pulling her friends together and travelling through time to prevent Lord Abigail from acquiring the Ring of Everything so vital to her plans.
